Abstract

Liquid waste from the steel industry processing, washing machine, and kitchenware foundry contained the elements of copper (Cu), chromium (Cr), and manganese (Mn). The effluent samples were destructed using concentrated HNO3. Then determined the concentration of the elements copper (Cu), chromium (Cr), and manganese (Mn) using an Atomic Absorption Spectrophotometer with a calibration curve. The results obtained for the level of copper (Cu) on the sample inlet was 0.9714 mg/L to 0.9719 mg/L, and the sample outlet was 3.9990 mg/L to 4.0002 mg/L. Levels of the element chromium (Cr) on sample inlet was 0.0295 mg/L to 0.0297 mg/L, the sample outlet was 0.0399 mg/L to 0.0400 mg/L. Meanwhile, the level of manganese (Mn) in the sample inlet was 0.1269 mg/L to 0.1271 mg/L in a sample outlet was 2.9699 mg/L to 2.9701 mg/L. Then the steel industry wastewater for elemental copper (Cu) and manganese (Mn) exceeded the limits that have been instituted by the Minister of Environment Decree No. 51, 1995, regarding the Liquid Waste Quality Standard for Industrial Activity.

Abstract

Liquid waste from the steel industry processing, washing machine, and kitchenware foundry that is disposed containing copper (Cu), chromium (Cr) and manganese (Mn) elements which is harmful to enviromental. The levels of elemental copper (Cu), chromium (Cr), and manganese (Mn) were analyzed using Atomic Absorption Spectrophotometry (AAS) method. The effluent samples were destructed with the addition of concentrated HNO3. Then determining of the concentration of the element copper (Cu), chromium (Cr) and manganese (Mn) using Atomic Absorption Spectrophotometer with a calibration curve. The obtained results for the levels of copper (Cu) on the inlet samples were 0.9714 mg/L - 0.9719 mg/L, the outlet samples were 3.9990 mg/L - 4.0002 mg/L. Hence, the levels of the element chromium (Cr) on inlet samples were 0.0295 mg/L - 0.0297 mg/L, the outlet samples were 0.0399 mg/L - 0.0400 mg/L and the levels of manganese (Mn) in the inlet samples were 0.1269 mg/L - 0.1271 mg/L in a outlet samples were 2.9699 mg/L - 2.9701 mg/L. Then the steel industry wastewater for elemental copper (Cu) and manganese (Mn) has exceeded the limits that have been instituted by the Minister of Environment Decree No. 51, 1995, about the Liquid Waste Quality Standard for Industrial Activity
