Abstract
Removal of sulphur dioxide from aqueous solution of sulphur dioxide using Macrotyloma uniflorum Lam. (horse gram) seed powder as an adsorbent was carried out in present study. The results showed that percentage removal by M. uniflorum seed powder at low concentration was 98% and 90% at high concentration. Batch adsorption was conducted with respect to contact time, concentration, and M. uniflorum seed powder dosage. It was shown that the optimum dosage was 0.4 g and optimum absorption time was 20 minutes.

Keywords Macrotyloma uniflorum;adsorption;unimolecular layer;contact time;adsorbent dosage.
