Analysis of the Leaching Out Test on Solidification/Stabilization of Cu(II) Ions Using Polyacrylamide

Abstract

Copper metal (Cu) is one of the dangerous heavy metals. Copper metal (Cu) is one of the dangerous heavy metals. An increase in Cu levels that is too high and exceeds safe limits will have a negative impact on living things because it is carcinogenic and accumulates in body tissues. At that level, there will be no accumulation of Cu (II) in the normal body. The existence of heavy metal waste with high concentrations in the environment can endanger various species of life. An increase in Cu levels that is too high will have a negative impact on living things. This research was conducted using the solidification/stabilization(s/s) method using a mixture of CuC_l2 metal ions and polyacrylamide binding agent (PAM) using a variety of different PAM concentrations, namely: 500 mg/L, 1000 mg/L, 1500 mg/L, 2000 mg/L and 2500 mg/L. This binder aims to reduce Cu(II) heavy metal contaminants/pollution in the environment and in industrial waste. This study aims to determine the interaction between Cu(II) metal ions and polyacrylamide mixtures. Interactions on polyacrylamide and Cu(II) mixtures were identified using the AAS instruments. Leaching out value of Cu(II) ion test with polyacrylamide obtained was 0.92%; 1.04%; 1.11%; 1.12%; 1.19%. The percentage results of the leaching out test from a mixture of Cu(II) ions and polyacrylamide showed a small value.
