Penentuan Kadar Logam Kromium (Cr), Zink (Zn), dan Selenium (Se) pada Air Sungai Denai dengan Metode Inductively Couple Plasma (ICP)

Abstract

There are three parameters to determined water quality, those are parameter of chemistry, parameter of physic, parameter of biology. In this study, used parameter of chemistry to determine zinc (Zn), chromium (Cr), and selenium (Se) are done with Inductively Couple Plasma (ICP) method, where for the result of zinc, chromium, and selenium levels made in mg/L. The analisis result are gotten that zinc : 0,00405 mg/L, chromium : 0,04042 mg/L, and selenium : 0,00033 mg/L. From the analysis result are gotten that zinc, chromium, and selenium levels in water bodies of water still in normal range that according to Government’s Rule Number 82 of 2001, where standart quality of zinc, chromium, and selenium in water bodies of water are 0,05 mg/L, 0,05 mg/L , and 0,01 mg/L.
