Abstract

Anionic clay hydrotalcite was used as an adsorbent to remove amido black dye from aqueous solutions. Response surface methodology (RSM) based on a jive-level, four-variable Central Composite Rotatable Design (CCRD) was employedto evaluate the interactive effects ofvarious optimization parameters. The parameters were contact time (6-10 hrs), solution pH (4-8), adsorbent dosage (200-600 mg) and dye concentration (50-100 mg//). Simultaneously increasing contact time, initial concentration andamount ofadsorbent dosage increased the quantity ofamido black dye removed. The optimum conditions derived via RSM for the reaction were a reaction time of 8.48 hrs, a concentration of58.09 mg/l, an adsorbent dosage of431.24 mg/L anda solution pHof6.27. The experimental percentage removal was 85.55 % under optimum conditions, which compares well with the maximum predicted value of 87.95 %.
