Penentuan Kadar Sulfat (SO42-) Pada Air Tanah Daerah Hamparan Perak dengan Metode Spektrofotometer UV-Visible

Abstract

Determination of sulphate (SO42-) contents on the groundwater belongs to Hamparan Perak region has been carried out . This research aims to determine the sulphate contents contained in groundwater which will then be compared with the standard quality standards of clean water quality according to PERMENKES RI No. 32 of 2017. The research method is UV-Vis Spectrophotometry with a wavelength of 420 nm and the measurement results are expressed in mg/L units. The result data show that sulphate level of Hamparan Perak’s groundwater 15,1346 mg/L. The result of this data indicate that the sulphate contents on groundwater in Hamparan Perak area recognice to the quality standards of clean water quality according to PERMENKES RI No. 32 of 2017, which the maximum content is 400 mg/L.
