Constructed wetlands (CWs) are extensively used as an economical and environmentally friendly sewage treatment under ecological engineering technology. Knowledge of the oxygen in the rhizosphere is of primary importance in understanding the function and regulation of microbial communities and macrophytes. Numerous studies on radial oxygen loss (ROL) have greatly elucidated the mechanism of contaminant removal in CWs. The main sources of oxygen in CWs are atmospheric reoxygenation, macrophyte transmission, and artificial aeration. However, artificial aeration is very expensive, and atmospheric reoxygenation is limited. Therefore, ROL by macrophytes is an essential and economical approach for oxygen input in CWs. In this review, we attempted to study the role of macrophytes in CWs. We described the mechanism of ROL and summarized the methods for determining ROL. We also investigated the role of ROL in contaminant removal in CWs. This review will provide considerable useful information on the oxygen input of CWs.

Abstract. Industrial company such as textile, leather, cosmetics, paper and plastic generated wastewater containing large amount of dye colour. The removal of dye materials are importance as the presence of this kind of pollutant influence the quality of water and makes it aesthetically unpleasant. As their chemical structures are complicated, it is difficult to treat dyes with municipal waste treatment operations. Even a small quantity of dye does cause high visibility and undesirability. There have been various treatment technique reviewed for the removal of dye in wastewater. However, these treatment process has made it to another expensive treatment method. This review focus on the application of adsorbent in dye removal from textile wastewater as the most economical and effective method, adsorption has become the most preferred method to remove dye. The review provides literature information about different basis materials used to produce activated carbon like agricultural waste and industrial waste as well as the operational parameters factors in term of contact time, adsorbent dosage, pH solution and initial dye concentration that will affect the process in removing textile dye. This review approach the low cost and environmental friendly adsorbent for replacing conventional activated carbon.

“…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.
