Analisa Kadar Sulfat dan Fosfat pada Hulu dan Hilir Air Sungai Deli secara Spektrofotometri Uv-Vis

Abstract

Analysis of sulphate and phosphate contents of Deli river water which are taken at Sibiru-biru and Pulo Brayan area have been carried out. Sulphate is determined by spectrofotometry uv-visible methods at was length 450 nm and posphate is determined at was length 880 nm. Sulphate contents of water sample which is taken at Sibiru-biru is 16 mg/l and sulphate contents Pulo Brayan water sample which is taken Pulo Brayan is 35 mg/l. If compare sulphate contents of water sample which is taken at Sibiru-biru and Pulo Brayan are fulfill with quality standart water second class (400 mg/l) while phosphate contents of water sample which is taken at Sibiru-biru is 47 mg/l and fulfill with quality standart water while phosphate contents of water sample which is taken at Pulo Brayan is 465 mg/l and not fulfill with quality standart water second class (0,2 mg/l).
