Utilization of HVS Paper Waste for The Manufacture of Oxalic Acid

Abstract

⎯ The purpose of this research is to determine the effect of time and temperature on the manufacture of oxalic acid from HVS paper waste by removing ink and alkali melting methods This research follows two steps i.e., pre-treatment and then paper hydrolysis. It was found that the average temperature that produces the most oxalic acid is at 80 min and 65°C, which is 3.9 g. The analysis results show that the melting point obtained is between 100-101 ° C. This corresponds to the actual melting point of oxalic acid based on the Indonesian National Standard (SNI) approximately 101-102°C.
