Penentuan Kadar Silika dalam Bahan Baku Aluminium Fluorida Secara Spektrofotometri

Abstract

Silicate determination at aluminium fluoride which is used as the main ingredient in aluminium smelting plant at PT.INALUM has been carried out. The silicate was measured using UV-Vis spectrophotometer at wave length 655 nm. The result was compared to Japan International Industrial Standard. The results analysis show that the average of silicate in aluminium floride is 0,00763 % amd according to requirements as ingredient in the process of electrolysis of alumina into aluminium at PT.INALUM
