The rapid development of some industries generates a huge amount of useless biowastes. Recently, biosorption, which can use biowastes as biosorbents, has attracted attention as an environmentally friendly method for the removal of ionic pollutants from wastewaters. For this reason, many researchers have investigated the biosorption capacities of various biowastes. In this study, fermentation waste (Escherichia coli) was used as a biosorbent for the removal of various organic and inorganic pollutants: i.e., cationic dye (methylene blue (MB)), anionic dye (Reactive Red 4 (RR4)), cationic metal (cadmium (II)), and anionic metal (arsenic (V)). The uptake of the cationic pollutants by the biosorbent increased as solution pH was increased. The RR4 uptake increased with a decrease in solution pH. In the case of the anionic metal (As (V)), it was not well removed in the range of pH 2-7. To examine adsorption rates and mechanisms, kinetic and isotherm experiments were conducted, and various kinetic and isotherm models were used to fit the experimental data. The maximum adsorption capacities of MB and RR4 were predicted to be 231.3 mg/g and 257.6 mg/g, respectively. In conclusion, fermentation waste (E. coli) is a cheap and abundant resource for the manufacture of effective biosorbents capable of removing both cationic and anionic (in) organic pollutants from wastewaters.
