Analisis Kandungan Ion Besi (Fe3+) dan Ion Tembaga (Cu2+), Total Padatan Terlarut (TDS) dan Total Padatan Tersuspensi (TSS) di dalam Air Sumur Bor di Sekitar Kawasan Industri Medan

Abstract

The level of Iron ion (Fe3+), Copper ion (Cu2+), TDS, and TSS had been determined in artesian well outside residents in Medan Industrial Park and residents around Medan Industrial Park. The water sampling were prepared by a wet digestion method with concentrated nitric acid as a solvent. Determined using Atomic Absorption Spectrophotometer at λspesific 248,3 nm for iron metal ion (Fe3+) and at λspesific 324,7 nm for copper metal ion (Cu2+). TDS and TSS determination using Gravimetric Method. The results of analysis shows that level of iron ion (Fe3+), copper ion (Cu2+), TDS and TSS in artesian well outside residents in Medan Industrial Park respectively as 11,7341×10-2 ppm ; 0,6611×10-4 ppm ; 133,4720 ppm ; and 0,1666 ppm. Level of iron ion (Fe3+), copper ion (Cu2+), TDS and TSS In artesian well around residents Medan Industrial Park respectively as : 42,2113×10-2 ppm ; 9,8798×10-4 ppm ; 370,5380 ppm ; and 0,2646 ppm
