| 1 | Biosorption of clofibric acid and carbamazepine in aqueous solution by agricultural waste rice straw显示文摘Due to their widespread use, clofibric acid(CA) and carbamazepine(CBZ) have been frequently detected simultaneously at relatively high concentrations in aquatic environments. In this study, agricultural waste rice straw was employed as a potentially low-cost, efective and easy-to-operate biosorbent(RSB) to remove CA and CBZ. The adsorption of both pharmaceuticals followed pseudo second-order kinetics, and intraparticle difusion was an important rate-limiting step. The adsorption isotherms of both drugs were fit well with Freundlich model. The adsorption of CA onto RSB was exothermic and was more likely to be dominated by physical processes, while the adsorption of CBZ was endothermic. Solution pH was determined to be the most important factor for CA adsorption, such that the adsorption capacity of CA onto RSB increased with the decline of solution pH. In the lower range of solution pH below 3.1, the CA removal efciency was enhanced with the increase of biosorbent dosage. The CBZ removal efciency was enhanced with the increase of RSB dosage without pH control. The maximum adsorption capacities were 126.3 mg/g for CA and 40.0 mg/g for CBZ. | Zhanguang Liu Xuefei Zhou Xiaohua Chen Chaomeng Dai Juan Zhang Yalei Zhang | 2013 | Journal of Environmental Sciences2013，25，12： | 6 |
| 2 | Zero-valent iron doped carbons readily developed from sewage sludge for lead removal from aqueous solution显示文摘Low-cost but high-efficiency composites of iron-containing porous carbons were prepared using sewage sludge and ferric salts as raw materials. Unlike previous time- and energy-consuming manufacturing procedures, this study shows that pyrolyzing a mixture of sludge and ferric salt can produce suitable composites for lead adsorption. The specific surface area, the total pore volume and the average pore width of the optimal composite were 321 m2/g, 0.25 cm3/g, and 3.17 nm, respectively. X-ray diffraction analysis indicated that ferric salt favored the formation of metallic iron, while Fourier transform infrared spectroscopy revealed the formation of hydroxyl and carboxylic groups. The result of batch tests indicated that the adsorption capacity of carbons activated with ferric salt could be as high as 128.9 mg/g, while that of carbons without activation was 79.1 mg/g. The new manufacturing procedure used in this study could save at least 19.5 k J of energy per gram of activated carbon. | Yiming Su Xiaoya Sun Xuefei Zhou Chaomeng Dai Yalei Zhang | 2015 | Journal of Environmental Sciences2015，27，10： | 2 |
