Abstract

Background:
Ammonia nitrogen at high concentration poses several threats to the human and environment such as odor and eutrophication. Although many techniques have been studied for ammonia nitrogen removal, utilization of fruit wastes as natural adsorbent could offer some advantages such as low cost and spent adsorbent can be used as fertilizer.
Aim:
The performance of jackfruit (Artocarpus heterophyllus) seed adsorbent for ammonia nitrogen (NH3-N) removal from aqueous solution was examined through batch and continuous bed column experiments. The effects of sodium chloride (NaCl) and lignin concentration on the adsorption process were evaluated.
Results And Discussion:
The results revealed that the adsorption performance gradually decreased upon the addition of NaCl and lignin in the solution. Fixed bed column experiments showed that maximum removal of ammonia nitrogen was …
