Six samples of dyeing industry wastewater were collected in plastic cans, which were already washed and rinsed with distilled water, from a dyeing industry at Tirpur. A typical treatment consisted of agitating 0.5 g of adsorbent and 100 ml of wastewater in 300 ml bottles at 120 rpm using a mechanical shaker. These bottles were withdrawn from the shaker at predetermined times. The sample was separated by centrifugation at 1000 rpm and the supernatant was analysed using an UV-spectrophotometer (U-3210, Hitachi, Japan). The adsorbent dose was varied from 0.5 to 3.5 g per 100 ml wastewaters and the pH from 1 to 9 using HCl or NaOH. The analysis of wastewater was carried out using standard methods (APHA, 1980). Experiments were carried out in duplicate and the maximum deviation was 3%.
