“…The negative entropy DS°r eflects the decreased randomness at the solid/solution interface during the MB biosorption [75,76]. Similar results were reported by Barka et al [27] and Han et al [77] where MB was adsorbed on Scolymus hispanicus L. and Fallen phoenix tree's leaf, respectively.…”

In the present study, biomass fiber (Luffa cylindrica) has been successfully used as biosorbent for the removal of a cationic dye namely, methylene blue, from aqueous solution using a batch process. The characterization of the biosorbent was carried out by the infrared spectroscopy (FTIR) and scanning electron microscopy (SEM). The chemical composition has been established by the energy dispersive X-Ray spectroscopy (EDS). The effects of various parameters such as the contact time (0-160 min), solution pH (2-10), biosorbent dose (0.5-8 g L -1 ), particle size, initial MB concentration (20-300 mg L -1 ) and temperature (20-60°C) were optimized. The biosorption isotherms were investigated by the Langmuir, Freundlich, Dubinin-Radushkevich and Tempkin models. The data were well fitted with the Langmuir model, with a maximum biosorption capacity of 49.46 mg g -1 at 20°C. The kinetics data were analyzed by the pseudo-first-order and pseudo-second-order models. The mass transfer model in terms of interlayer diffusion was applied to examine the mechanisms of the rate-controlling step (R 2 = 0.9992-0.9999). The thermodynamic parameters: free energy (DG°= -5.428 to -3.364 kJ mol -1 ), enthalpy (DH°= -20.547 kJ mol -1 ) and entropy (DS°= -0.052 kJ mol -1 K -1 ) were determined over the temperatures range (20-60°C). The results indicate that Luffa cylindrica could be an interesting biomass of alternative material with respect to more costly adsorbents used nowadays for dye removal.

“…The use of high-incarbon content plant leaves in manufacturing AC has been suggested to attain a significant positive ecological impact and a simple and cheap method for the adsorption of organics such as dyes from aqueous solutions [33,34]. The applications of ACs are involved in many fields that can be used as a green adsorbents for separation, purification, decolorization and deodorization, of vegetable oils and fats, water purification and pollution treatment, air and gas purification (cigarette filters, motor vehicles exhaust control), and food and pharmaceutical industries [35][36][37].…”

“…In the last few years, the consumption of coffee has rapidly increased, especially by young people. According to a survey done by Sulyman (2016) [5], which included 25 cafes in the city of Tripoli, Libya, the average generation of coffee ground wastes by only the 25 cafes is estimated to be in the range of (36)(37)(38)(39)(40)(41)(42)(43)(44)(45) tons annually, and a big volume of this waste is still kept in big plastic bags for disposal by conventional methods, which are burned or dumped. It is also estimated that in one of these cafes, more than 100 cups of coffee are drunk within an hour, while in the city of Gdansk, Poland, at one café that was surveyed, more than 1,600 cups of coffee are consumed daily.…”

A major threat to the comfort of human life has been imposed by increased industrialization and urbanization. The generation and disposal of huge amounts of toxic materials and pollutants have heavily contaminated our environment. Some Organics such as synthetic dyes (SD) and heavy metals (HM) are becoming increasingly prevalent as the most dangerous pollutants in soil and surface water environments. They are causing great concern worldwide due to their toxicity to many life forms.Environmentally friendly utilization of agricultural by-products/waste materials either as raw materials or in production of so-called activated carbons (AC) is an important issue. Because it is apparent from our literature review that the main factors characterizing these materials are their affordability, local availability, and efficiencies in removing many unwanted toxics and pollutants, they therefore could be utilized instead of more conventional but expensive adsorbent materials, particularly in developing countries where many industries lack appropriate individual sewage treatment systems; even where they exist, they lack satisfactory functioning and maintenance because of the lack of good budgets.A number of case studies are supplied in this review. These case studies have pointed to the efficient removal of SD/HM ions from aqueous solutions by the agricultural by-products/wastes in the form of a raw material, signifying spent tea leaves (STL) as a good example. Besides, the efficient removal of such ions by AC produced from these agricultural by-products/wastes has also been given in detail, suggesting a variety of AC agricultural by-products/wastes sources. Both kinds are widely used adsorbents in the treatment of wastewaters. Our review has shown that these adsorbents are characterized by many exceptional physical and chemical features that make them widely used adsorbents in the treatment of wastewaters. The adsorption efficiencies by these substances were also affected by the characteristics of AC, which depend on the physical and chemical properties of the precursor (i.e., agricultural by-products/wastes) as well as on the activation method applied, which is either chemical or physical. The structural properties of the resulting
