Abstract

Zn2+ is a harmful ion generated from industrial waste that must be overcome. Zn (II) absorbed in excess conditions can interfere with body health and cause system dysfunction. Metal ion absorption is carried out using langsat fruit peel biosorption. Langsat fruit peel contains active functional groups that have the potential as a binding agent for Zn2+ metal ions. This study aims to determine the optimum conditions for the absorption of Zn2+ ions using langsat fruit peel on the effect of particle size and flow rate on the column. the results showed that the biosorbent was able to absorb Zn ions of 12.2994 mg/g at a particle size of 106 micro and 12.6275 mg/g at a flow rate of 1 ml/min. this shows that langsat fruit peel is one of the best biosorbents in absorbing metals with large absorption capacity data.

Abstract

Excessive discharge of heavy metals in the environment can have negative effects on the environment and human health. environment and human health, one of which is the metal ion Zn2+. To overcome the increase in heavy metals biosorption method is used. The purpose of this study is to determine the general conditions of the initial concentration of Zn2+ that can be absorbed by langsat skin as well as the isotherm used. The results showed that optimum absorption of Zn2+ metal ions occurred at an initial concentration of 400 ppm solution and decreased with increasing concentration. The optimum absorption of Zn2+ metal ions occurs at an initial concentration of 400 ppm solution and increases with increasing concentration and decreases when it reaches the optimum state. The maximum absorption capacity obtained was 11.7168 mg/g. The capacity of biosorption of Zn2+ ions fulfills the Langmuir Isotherm equation with R2 of 0.9994.
