of volcanic filter material on biosorption of Cu2+ with immobilized strain 从图1可以发现:将未挂膜的火山岩滤料用于Cu2+的吸附时,在各初始质量浓度的溶液中吸附12 h后,与吸附前废水中Cu2+质量浓度相比基本无变化.由此可见该火山岩颗粒对Cu2+没有亲和力,不具有吸附作用. 2.2 不同BAF参数条件对固定化菌株吸附重金属铜的性能分析 2.2.1 进水pH 在水力停留时间2 h,气水质量比为2:1,进水Cu2+质量浓度为50 mg/L的条件下,进水pH与Cu2+去除率关系试验结果如图2所示. 图2 pH对固定化菌株吸附Cu2+性能的影响 Fig. 2 Effect of pH on biosorption of Cu2+ with immobilized......
out to investigate metal biosorption properties of BF. The factors affecting the adsorption of cadmium, such as pH, initial concentration, contact time, coexisting ions were studied. 2 Experimental... on Cd adsorption pH is a key parameter, along with metal concentration and solution composition, in determining biosorption levels. The objective of this study was to determine the effects of pH......
