Penentuan Kadar Mn pada Air Mineral Aqua PT. Tirta Sibaykindo Menggunakan Penyaring Green Sand dengan Metode Spektrofotometri

Abstract

It has been done for the determination of manganese after green sand by using spectrophotometer with a wavelength of 525 nm. From the data obtained by the concentration of manganese before green sand are 0,075 mg/L, 0,096 mg/L, 0,081 mg/L, 0,01 mg/L, dan 0,087 mg/L, while after green sand are 0,048 mg/L, 0,041 mg/L, 0,05 mg/L, 0,059 mg/L, dan 0,054 mg/L.
