Abstract
In order to understand the adsorption properties of insect feces on heavy metals, White grubs feces and Black soldier fly larvae (BSFL) feces were selected as the adsorption materials to study the adsorption properties of insect feces on Cu2+ and Cd2+. The results showed that the adsorption effect increased significantly with the increasing of the amount of insect feces, and the best adsorption effect were 2g White grubs feces and 4g BSFL feces in 100ml (10mg/L) Cu2+ and Cd2+. With increasing of concentration Cu2+ and Cd2+ (0-20 mg/L), the adsorption quantity of Cu2+ and Cd2+ increased. Adsorption quantity of BSFL feces for Cu2+ was more than White grubs feces, while for Cd2+ was less than White grubs feces when concentration of Cd2+ was over 10mg/g. With the increase of pH, the adsorption rate of White grubs feces and BSFL feces on Cu2+ and Cd2+ decreased significantly.
