Abstract

In the present study, an adsorbent was prepared from Ben Teak sawdust by chemically treating and carbonizing with phosphoric acid. Using Design Experts software, 2 level factorial studies and Response surface methodology studies using Box-Benkhen design model were carried out and a relationship between Qe and pH, temperature, concentration of dye, amount of adsorbent, agitation speed were derived for Congo red- Saw Dust Carbon(SDC). Maximum Congo-red removal of 96.764 % and adsorption capacity of 149.507 mg/g was found at pH 2, 30 °C, 125 rpm, 150 mg/L and 1gram/L of reaction mixture for an optimum contact time of 2.5 hours. Adsorption isotherm obtained fitted well into both Freundlich and Langmuir equation but Freundlich isotherm fits better with 1/n ranging from 0.4944 to 0.5894 and R2 ranging from 0.92333 to 0.952. The qmax from Langmuir isotherm was established to be 209.7 mg/g.
