Phenol removal from wastewater is very widely studied area of research. The practical approach for phenol removal by adsorption involves study of batch adsorption and more importantly the fixed bed operation. In the present study, various aspects of fixed bed adsorption for phenol have been discussed. The review of research carried out on this topic is presented. The phenol removal in fixed bed...

The present work deals with the continuous flow systems based on renewable resource biosorbents towards green removal of various categories chemical pollutants from aqueous media. opening discussions are focused on: (a) resources; (b) (c) dynamic biosorption. After these, resources reviewed according to parameters breakthrough curves. Subsequently, targeted systematized and analyzed following c...

Contaminants of emerging concern (CECs) are chemicals or materials that not under current regulation but there increasing concerns about their possible occurrence in the environment because potential threat to human and environmental health, with wastewater perceived as primary source. Although various techniques for removal from water have been studied, it should be emphasized choice also cons...

During the last two decades, extensive attention has been paid on the management of environmental pollution causal by hazardous materials such as heavy metals. Decontamination of heavy metals in the soil and water around industrial plants has been a challenge for a long time. A number of methods have been developed for the removal of heavy metals from liquid wastes such as precipitation, evapor...

Industrial effluents loaded with heavy metals are a cause of hazards to human and other forms of life. Conventional methods such as precipitation, evaporation, electroplating, ion exchange, membrane processes, etc. used for removal of heavy metals from waste water however, are often cost prohibitive having inadequate efficiencies at low metal ion concentrations. Biosorption can be considered as...

Novel, functional materials based on chitin of marine origin and lignin were prepared. The synthesized materials were subjected to physicochemical, dispersive-morphological and electrokinetic analysis. The results confirm the effectiveness of the proposed method of synthesis of functional chitin/lignin materials. Mechanism of chitin modification by lignin is based on formation of hydrogen bonds...

Biosorption on lignocellulosic wastes and by-products has been identified as a proper alternative to the existing technologies applied for toxic metal ion and dye removal from wastewater streams. This paper deals with utilization of typical low cost wastes and by-products produced in different food agricultural and agro-industries as biosorbent and reviews the current state of studies on a wide...
