Abstract: Adsorbent material derived from tamarind-seed testa was studied for acid dye adsorption. Acid dyes are water-soluble dyes preferred for industrial dyeing of nylon. In this research, the dye adsorbed efficiencies of three readily water-soluble acid dyes, namely Nylosan Red E-BL (NR), Nylosan Yellow S-L sgr (NY) and Moderacid Yellow GL (MY) were investigated. From the results, it was found that 1 kg tamarind seeds could be prepared into 55 g adsorbent material. The adsorbent was capable of adsorbing the acid dyes well under pH 5 condition with a rapid adsorption taking place within the first 15 minutes of adsorption process. After that, the adsorption increased gradually until reaching equilibrium after 2-3 hours depending on the structures of acid dyes. Adsorption behavior of NR was fitted with both Langmuir and Freundich isotherms while NY and MY adsorptions corresponded to Langmuir and Freundich isotherms, respectively.
