摘要：

Water treatment by adsorption methodology is being evolved in recent years. Various researchers are searching new adsorbents for water treatment which can replace activated charcoal. In the following study, the efficiency of removing Congo Red dye from water using two novel adsorbents, i.e. Raphanus sativus (Radish) peels and Greivia asiatica (Phalsa) leaves was evaluated and compared with activated charcoal. The adsorption process is carried out batch wise by using different concentrations of the aqueous dye solution with different adsorbent doses, agitation rate, varying contact time intervals, at a range of initial pH values and at different temperatures. Various chemicals were used for enhancing the adsorption capacity of adsorbents. The suitability of the adsorbent for using it is tested by fitting the adsorption data on Langmuir isotherm. The results showed that the Phalsa leaves powder is more effective adsorbent than Reddish peels for removing Congo Red dye from water. It can be used for removing Congo Red dye from waste water.
