Lignocellulosic-Based Sorbents: A Review

The combustion of fossil fuels is intensifying global warming and destructing the ecosystem with negative human health impacts as well. Even so, other anthropogenic activities have unfortunately constituted pollution also to our environment, say, in form waste waters. Beside these, existing technologies for water treatment problems such high costs, sludge disposal challenges, etc. Thus, it now important find economically viable safe alternatives decontaminate Hence, low cost, renewable, easily accessible, readily prepared biosorbents become favourable traditional counterpart elimination pollutants from aqueous systems. Fortunately, these requisite comparable properties necessary adsorption pollutants. Many studies been reported on application removal. However, this paper provides an overview preparation, properties, their applications removal related use. Biosorbents are usually used raw or processed forms activated carbon (AC), biobar (BC), charcoal (CC) pharmaceuticals, pesticides, organics, inorganics, mycotoxins, Besides classical sorption pollutants, prospect electrodes microbial fuel cells, green packaging materials, energy storage devices, catalysts, soil remediation agent, sequestration, further concerted investigations should be exercised develop feasibly best conditions preparations modifications biosorbents. In addition, mean pore size, size distribution, porosity, surface functionality, zeta potential had about biosorbents, especially novel types. There need development specific tasks. Another essential thing determine desorption Focus directed more sustainable enhance Again, suggested that suitable biomasses identified enable successful preparation efficient More can recycled after use avoid littering possible pollution.
