Analisa Sianida Bebas pada Air Minum dan Total Suspended Solid pada Air Limbah dengan Metode Spektrofotometri di BTKLPP

Abstract

Analysis of Free Cyanide in Drinking Water and Total Suspended Solids in Wastewater has been conducted at the Environmental Health and Disease Control Technical Institute (BTKLPP) using the NOVA-60 Spectrophotometer at a wavelength of 60 nm. The analysis results revealed that the CN- concentration in the drinking water samples was 0.002 mg/L, <0.002 mg/L, <0.002 mg/L, 0.003 mg/L, and 0.002 mg/L. The Total Suspended Solids level was found to be 22 mg/L, 17 mg/L, 15 mg/L, and 106 mg/L. Based on the results, the CN- concentration in the drinking water samples already complies with the standard limit set by the Ministry of Health Regulation 492/MENKES/PER/IV/2010, which is 0.07 mg/L. The analysis results for Total Suspended Solids indicate that three samples meet the standard limit, while one sample exceeds the standard limit based on Regulation P.16/MENLHK/SETJEN/KUM.1/4/2019, which is 50 mg/L.
