Composts as Biosorbents for Decontamination of Various Pollutants: a Review

Biosorption is a low-cost green technology for water pollution decontamination. Recently, new adsorbent materials (raw or modified) were synthesized and tested in a wide variety of different pollutants. Among them, researchers pay attention on an alternative use of composts. The major use of composts is as soil amendments to improve the fertility of soils. For the first time in literature, the present review article gathers information about the applicability of compost materials as biosorbents in batch modes. For this purpose, equilibrium modeling and isotherm, kinetic, and thermodynamic studies were discussed in details. Moreover, many parameters such as temperature, pH, and contact time were also analyzed. The main pollutants studied in this work are dyes and heavy metals either in single- or multi-component systems.
