KEMAMPUAN SERAPAN ABU TULANG KAMBING TERHADAP VARIASI KONSENTRASI ION SULFAT

Abstract

Calcium oxide was a major component in bone ash. This calcium oxide has relatively opened structure, so it can be used as an adsorbent. Its adsorption ability on sulfate ion has been analyzed in an solution. The analysis of sulfate ion was carried out using Spectrophotometer UV-VIS by turbidimetry method. The results showed that concentration of bone ash affected to the adsorption of sulfate ion with optimum adsorption of 80.833% at 10 ppm of bone ash.
