Seed husk of Bengal gram (SHBG) (Scientific Name: Cicer arietinum) was used as an adsorbent for the removal of a direct dye namely Congo red (CR), two basic dyes namely methylene blue (MB) & rhodamine-B (RB) and an acidic dye namely acid blue 25 (AB) from aqueous solutions with equilibrium isotherms. The effect of particle size, of mass of adsorbent, of agitation speed of shaker and of temperature of dye solutions was studied for understanding the interaction of dyes with adsorbent. The uptake of dyes by the adsorbent was increasing with increasing mass of the adsorbent, decreasing with increasing size of the adsorbent, and increasing with increasing agitation speed and temperature.
