摘要
Abstract
The organic modification bentonite loaded with the ferric hydroxide can be made through using the organic bentonite with the good absorptive property as the carrier, and the adsorption experiment of waste water with chromium (Ⅵ) is carried out by the modified composite adsorbent obtained. The results indicate that the removal efficiency of waste water with Cr(Ⅵ) is good when the mass fraction of modification bentonite is 3%. The removal ratio of waste water with 10 mg/L Cr(Ⅵ) can reach 98.37% under the following conditions: the dosage of composite adsorbent is 1.0 g; the temperature is 25℃ and the oscillating time is 4 hours.关键词
