摘要
利用出芽短梗霉进行吸附水体中Cr(Ⅵ)、Cd(Ⅱ)共存离子实验, Cr(Ⅵ)、Cd(Ⅱ)毒性浓度均为300 mg/L时,菌种生长良好。吸附性能实验结果表明:出芽短梗霉吸附水中Cr(Ⅵ)的最佳条件是pH值为3.0、时间为2 h、温度为30℃,吸附量为8.575 mg/g;吸附Cd(Ⅱ)的最佳条件是pH为5.0、时间为30min、温度为30℃,吸附量为15.49 mg/g。
The authors focuse on the experiment taking advantage of Aureobacidium pullulans to adsorb chromium(Ⅵ) and cadmium(Ⅱ) ions coexisting in water body. The bacteria culture grows well under the condition that the toxicity concentrations of chromium(Ⅵ) and cadmium(Ⅱ) ions are 300 mg/L, respectively. The adsorptive experiment illustrates that the adsorption quantity of chromium(Ⅵ) is 8.575 mg/g on the optimum condition that pH is 3, adsorption time is 2 h and the temperature is 30℃; The adsorption quantity of cadmium(Ⅱ) is 15.49 mg/g on the optimum condition that pH is 5, adsorption time is 30 min and the temperature is 30℃.
