“…The suitability of the Langmuir isotherm to fit the data was confirmed by the exponent value of the Redlich-Peterson model, n, which was near to one. It should be noted that most of the isotherm adsorption studies of pharmaceutical products on various adsorbents follow the Langmuir isotherm model [26][27][28][29][30][31][32][33][34][35]. The monolayer adsorption capacity, qm, was found to be 4.21 mg g -1 .…”

Caffeine is a chemical compound that has been detected in the environment and belongs to some of the most popular emerging pollutants that may cause serious environmental and human health problems. In this study, the adsorption of caffeine on groundnut shell as low cost adsorbent was investigated using the batch equilibrium method. Three adsorption isotherms namely the Langmuir, Freundlich and Redlich–Peterson isotherms in their non-linear forms were applied to the adsorption equilibrium data. Both the Langmuir and Redlich–Peterson models were found to fit the adsorption isotherm data well. The retention of caffeine on the groundnut shell showed a relatively significant adsorption with a maximal quantity of 4.21 mg g-1. The present study showed that the powdered groundnut shell is a promising and alternative adsorbent for the removal of caffeine from aqueous solutions.

“…The modern studies that emphasize the extensive utilization of waste cotton cloth concentrate on the extraction of some chemical compounds, such as cellulose nanocrystals [17] and extraction of nanocellulose through a novel one-pot isolation system [26]. Furthermore, a study on production of single and mixture adsorption was conducted by Boudrahem et al [27] and bacterial cellulose production by Feng et al [8]. Also, waste cotton cloth has been used for tensile and fatigue characterization in the area of polypropylene matrix for composites applications such as the industries dealing with automotive [28].…”

Assessing the performance of modified waste cotton cloth (MWCC) installed in a biological contact reactor as a biofilm carrier used for domestic wastewater treatment

The current study examined the performance of modified waste cotton cloth (MWCC) in the removal of organic pollutants from domestic wastewater as an emerging technique for waste textile resource management and reuse. The MWCC biofilm carrier was self-made with discarded cotton cloths cut into smaller strips with 66 cm long and average weight of 2.4 g each. The surface of the non-modified waste cotton cloth (NM-WCC) was modified through the hydrosulphuric acid (H 2 SO 4) method to enhance the physical characteristics of the material such as hydrophilicity and biofilm attachment. The best filling rate of the carrier used for the experiment was 65% as determined by preliminary studies. Two self-made biological contact biofilm reactors: R1 (installed with NM-WCC) and R2 (fixed with MWCC), were used for the experiment. The experimental results showed that MWCC had higher removal efficacy of chemical oxygen demand, ammonia-nitrogen (NH 4 +-N) and total phosphorus (TP) at 98.34%, 85.44% and 60.20%, respectively. The hydraulic retention time decreased from 21 to 8 h on the 4th day. The scanning electron microscope was used to analyse the surface characteristics of the NM-WCC and MWCC. The water-holding capacity of the biofilm carriers was determined through the static immersion method and ASTM D1117-80 guiding principles. The water contact angle was estimated through the static process by adapting Young's equation. The findings of this research could significantly contribute to the discovering of alternative innovative technological prospects of utilizing H 2 SO 4 MWCC as an effective biofilm carrier in domestic wastewater treatment.

“…For this reason, microextraction applications using waste products, such as cotton cloths waste, are increasingly appearing in scientific publications [65][66][67]. Cotton cloths waste has been used for the production of nanocellulose materials [68], including activated and porous carbon [69,70]. There are two main types of nanocellulose materials arising from cotton fibers, viz.…”

Returning to Nature for the Design of Sorptive Phases in Solid-Phase Microextraction

Green analytical chemistry principles aim to minimize the negative impact of analytical procedures in the environment, which can be considered both at close (to ensure the safety of the analysts) and global (to conserve our natural resources) levels. These principles suggest, among other guidelines, the reduction/minimization of the sample treatment and the use of renewable sources when possible. The first aspect is largely fulfilled by microextraction, which is considered to be among the greenest sample treatment techniques. The second consideration is attainable if natural products are used as raw materials for the preparation of new extraction phases. This strategy is in line with the change in our production system, which is being gradually moved from a linear model (take-make-dispose) to a circular one (including reusing and recycling as key terms). This article reviews the potential of natural products as sorbents in extraction and microextraction techniques from the synergic perspectives of two research groups working on the topic. The article covers the use of unmodified natural materials and the modified ones (although the latter has a less green character) to draw a general picture of the usefulness of the materials.Separations 2020, 7, 2 2 of 22 principle identifies one of the trends of current research in analytical sciences, it is difficult to be applied when complex samples containing the analytes at very low concentrations are processed. In such scenarios, the simplification of the sample treatment and the reduction of the sources applied (reagents, energy) can be a more practical objective, at least currently. Microextraction techniques fulfill the latter criteria [8], and they are considered among the greenest sample treatment techniques [9].Microextraction techniques have evolved in the last decade following some key trends. Among them, the development of new extraction phases can be highlighted, considering the context of this review article. In this evolution, the tenth (use of renewable resources) and eleventh (replace or remove toxic reagents) principles of GAC are especially relevant [7]. In the liquid microextraction context, environmentally friendly solvents [10,11] such as CyreneTM [12] and deep eutectic solvents [13] are clear examples of this progress.The paradigm of our production system, which up to now has been based on a linear "take-make-dispose" model, is progressively changed to a circular model [14] where reusing, repairing, refurbishing, and recycling appear as key terms. The use of surpluses of natural products as raw materials for the preparation of new sorbents is an interesting contribution of analytical chemistry for changing the production model. This review article, which combines the vision of two research groups working in the topic, tries to draw the general picture of the potential of natural products for the synthesis of new sorptive phases in solid phase extraction and solid phase microextraction. The article will cover strategies with different green characterist...
