Abstract

Pb metal is a heavy metal that comes from wastewater and can cause very big problems for organisms and the environment because it has high toxicity and is non-biodegradability. One way to solve the problem of heavy metal pollution is using the adsorption process. Duck eggshells are household and commercial waste that have not been utilized to their full potential. This study aims to determine the effectiveness of the adsorption of duck eggshells that have been activated physically and chemically by determining the optimum pH, optimum contact time, and optimum mass as well as knowing the characteristics and content of the egg shell ducks. Duck eggshells were physically activated by being heated in a high temperature of 900 0C and chemically activated through immersion process using H3PO4 for 24 hours. Pb Metal was measured using the Atomic Absorption Spectrophotometry tool at wavelength of 283.3 nm. The characteristics and content of duck eggshells were analyzed using the SEM-EDS tool. The results showed that the optimum condition of the duck eggshells in adsorbing Pb metal was at pH 6, optimum time at 75 minutes, and optimum mass of 500 mg with adsorption effectiveness of 94.75%. The results of the examination using the SEM tool showed that the duck eggshells that had been physically and chemically activated had larger pores compared to the duck eggshells that have not undergo the activation process. EDS analysis showed that the elements contained in the shell of duck eggs are carbon elements (C), oxygen (O), calcium (Ca), and phosphorus (P).
