Removal of Arsenic Ion from Aquatic Condiment Using Lignin

Abstract:

Removal of arsenic ion from fish condiment using lignin as adsorbent was investigated. The effects of pH of aquatic condiment solution, temperature, adsorption time, solid to liquid ratio, salt concentration and amino acid concentration on the removal ratio of arsenic ion from aquatic condiment were also studied. Removal ratio of arsenic ion reached 98.65% with pH 2, temperature 40 °C, adsorption time 25 min, solid to liquid ratio 1:70. It was confirmed that lignin can be used to remove arsenic ion from aquatic condiment.
