查询词典 bone char

When pH is 10, adsorption time is 30 min, dosage of bone char is 0.6 g/L, the original concentration of As in drinking water is 0.5 mg/L, As removal can reach 95.2%. The adsorption behavior is fitted both with Langmuir and Freundlich isotherm. The adsorption mechanism is supposed to be Ca—OH functional groups combined with anion. And there may occur the co-precipitation between calcium hydrogen arsenate and hydroxylapatite in the aqueous solution, and ions also exchange. The saturation adsorption capacity of As reaches 4.688 mg/g. Indexes of effluent are in good agreement with the WHO stringent drinking water standards (0.01 mg/L).

研究结果表明：在pH=10，吸附时间为30 min和骨炭加入量为0.6 g/L，饮用水砷初始质量浓度为0.5 mg/L时其砷去除率可达95.2%；骨炭吸附砷的行为同时符合Langmuir和Freundlich等温吸附模型；其吸附机理可能是Ca—OH官能团结合HASO4阴离子，并产生砷酸氢钙和羟基磷灰石的共沉淀，另外还存在离子交换作用；吸附柱的饱和吸附容量为4.688 mg/g；出水砷浓度符合世界卫生组织规定饮水砷标准(0.01 mg/L)。

Domino, the largest sugar producer in America, uses bone char to filter impurities from its sugar.

多米诺骨牌，美国最大的食糖生产商，使用骨炭过滤糖的杂质。

Methods Cost-utility analysis method was used to compare the two main defluoridation projects (digging low-fluoride well,bone char defluoridation) utility.

随机抽取107处工程，用质量调整生命年为改水的产出指标，分析工程的效用及效用比。

Under the field condition, effect of six amendments, including silican fertilizer, calcium magnesium phosphate fertilizer, lime and bone char and so forth, on in-situ chemo-immobilization of Cd in contaminated soils was investigated.

Many kinds of treatment are used for fluoride removal. Conventional methods including coagulant sedimentation, active alumina adsorption, bone char adsorption are not suitable for rural areas owing to operation and management. Membrane methods for defluoridation, such as electric infiltration and reverse osmosis, have the advantage of convenient application, simple operation and good adaptability.

用于饮用水除氟的水处理技术有多种，常规除氟技术的有混凝沉淀法、活性氧化铝吸附法、骨炭吸附法，常规除氟技术由于受技术操作、管理、运行等要求影响，不宜在农村使用，膜法除氟技术，如电渗析、反渗透等应用方便，操作简单，适宜性强。

The affecting factors of removal of arsenate As(Ⅴ by bone char were studied in batch and column experiments. The results show that the performance of bone char adsorbing As from drinking water is stable after adsorption—desorption—regeneration—re-adsorption cycles.

摘 要：采用骨炭作吸附剂，通过静态和动态吸附试验，研究饮用水中砷去除的效果及其影响因素，以及骨炭反复吸附—解吸—再生—再吸附后骨炭性能的稳定性。
