The use of mango seed arum manis type (mangifera indica L) as biosorbent

Abstract

This research was conducted to study the effectiveness of mango seed Arum Manis type as biosorbent. Methods used in study were pre-treatment and activation process. The mango seeds were cleaned, dried under the sun and crushed to pass through 140 mesh. And then they were activated with 3N chloric acid at certain ratio. After heating at 70 °C for two hours, cooling under room temperature, they were washed with aquadest. At last, the powder was activated physically (calcinating) at several temperature. The best condition for chemical and physical activation were concluded by taking the highest Iodine Number of each sample. Comparing to the standard of activated carbon issued by SNI 06-3730-1995 it was found that the highest of the Iodium Number was 803, 79 mg/g, ash content was 8 % and moisture content was 13, 3 % at condition the ratio of mango seed to 3N chloric acid 1:4 (w/v) and calcinating temperature 110 °C which means biosorbent from mango seed has met the standard from these three parameters.
