Penentuan Kadar Logam Fe, Na, Ca dan Mg dalam Dissolving Pulp di PT. Toba Pulp Lestari, Tbk

Abstract

Determination of Fe, Na, Ca and Mg metal content in dissolving pulp by complexometric titration method using Ethylene diamine tetra-acetic acid (EDTA) to determine the metal content of Calcium (Ca) and Magnesium (Mg), spectrophotometer DR 6000 to determine metal content Iron (Fe), and a flamephotometer to determine the metal content of Sodium (Na). Determination of metal content of Fe, Na, Ca and Mg in dissolving pulp was carried out on January 24 – February 4, 2022. The levels of Fe, Na, Ca and Mg metals obtained were 15 ppm, 300 ppm, 75 ppm and 150 ppm, respectively. These results indicate that the metal content of Fe, Na, Ca and Mg has met the standard specifications at PT. Toba Pulp Lestari, Tbk. Porsea.
