Analisa Kadar Sianida (Cn-) dan Sulfida (S2-) pada Air Bersih dengan Metode Spektrofotometri di Balai Teknik Kesehatan Lingkungan Pengendalian Penyakit (BTKLPP) Kelas 1 Medan

Abstract

Research on the analysis of Cyanide (CN-) and Sulfide (S2-) levels in clean water test samples at the Center for Environmental Health Engineering and Disease Control (BTKLPP) using the spectrophotometric method. This study aims to determine the levels of Cyanide (CN-) and Sulfide (S2-) in clean water and compare them with the quality standards set by Permenkes 32/Menkes/Per/2017 for Cyanide and PP No. 22 of 2021 for Sulfide. The results of the analysis carried out showed that the cyanide content of clean water still met the quality standard limit, namely 0.1 mg/L in test sample number 03 = 0.002 mg/L, number 81 = 0.003 mg/L, number 135 = 0.004 mg/L, and number 136 = 0.002 mg/L. Sulfide analysis results in the clean water test sample still met the quality standard limit of 0.02 mg/L in test sample number 03 = 0.0013 mg/L, number 129 = 0.0011 mg/L, and number 130 = 0.0015 mg/L
