in fly ash and modified materials were analyzed by the Jade 6.0 program. 3 Results and analyses 3.1 Effect of material ratio on equilibrium adsorption capacity of Cr(VI) The orthogonal adsorption.... Through the value of R, it can be concluded that there is a significant order of influencing factors in this experiment, which is A>C>B. Therefore, the factors affecting the adsorption capacity (q......
to improve the adsorption capacity of resin,a new cerium-loaded cation exchange resin arsenic adsorbent was prepared by impregnating cerium into the cation exchange resin.Batch adsorption experiments under...,such as nitrate,chlorate,sulphate and carbonate,showed no remarkable effect on As(Ⅴ)and As(Ⅲ)adsorption.The desorption and regeneration study showed that the adsorption capacity of Ce-loaded resin......

carbon (AC) was prepared from surplus sludge using chemical activation method with the assistance of ZnCl2. The influences of process parameters on the AC’s specific surface area and adsorption capacity... to a significant increase in adsorption capacity when the pH value varied from 3.0 to 7.0, and the optimal pH for removal of Pb2+ was 7.0. It was observed that the pseudo-second-order equation provided......
factor making some bacteria have a selective adsorption on different minerals[7-11], in which the bonding capacity of functional groups on cell surface to metal ions on mineral surface plays an important... with the mineral surface. In fact, the selective adsorption is the result of many groups bonding to one metal ion together. For above three strains of bacteria, the bonding capacity of some cooperated atoms......
Preparation and Characterization of Mg/Al/Fe Hydrotalcite with Superb Absorption Capacity toward Congo Red杨凯1,杜毅1,沈洁2,Lü Xingjie1,LI Zhongfu1,CHEN Zhongtao1,FENG Yibing1,DU Minxing1,ZHU Chaofeng11..., Fourier transformed infrared spectra, thermogravimetric analysis, and N2 adsorption-desorption.The morphology of MAF-LDH1 is petal-like with the size of 400-500 nm and the thickness about 10-20 nm......
to the mark of colorimetric tube, the absorbency was determined in a 1 cm colorimetric vessel at wavelength of 555 nm and compared with blank test. The adsorption capacity (Q) of Cu(II) on AA-PTFE...-Behnken design was used to develop a correlation between the adsorption conditions and adsorption capacity of AA-PTFE for Cu(II). A total of 17 runs for optimizing the three individual parameters......

and the result fits well with the pseudo-second order model.The key mechanism of adsorption is ion-exchange between metal and-ONa/H.According to the Langmuir isotherm model,the maximum capacity of Pb(Ⅱ) is 488.323 mg·g-1.The relatively low RL values indicate that Nb/TiNFs exhibit favorable adsorption of Pb(Ⅱ).Nb/TiNFs indicate high adsorption capacity over a broad pH range.Co-existing inorganic ions (Na......
) resin prepared under microwave irradiation were used for adsorbing Au(Ⅲ) ions in hydrochloric acid medium.The influence of pH and temperature on the adsorption capacity of XCCS was investigated.The... and the maximum adsorption capacity of Au(Ⅲ) ions on XCCS is observed at pH 1 and 20℃.The data of batch adsorption tests are fitted to kinetic models and isotherm models,respectively.The kinetics......
