Trans. Nonferrous Met. Soc. China 24(2014) 1912-1917 Thermodynamics and kinetics of adsorption for heavy metal ions from aqueous solutions onto surface amino-bacterial cellulose Min LU, Yue-ming... cellulose (amino-BC) was prepared by chemical modification of bacterial cellulose(BC). The adsorption characteristics and mechanism of amino-BC were studied. The results show that adsorption data can......
, China Received 16 March 2011; accepted 30 May 2011 Abstract: The influencing factors in adsorption such as adsorption time, pulp concentration, bacterial concentration, pH as well as ionic strength were investigated to explore the relationship among them and bacterial adsorption. The adsorption was a rapid process for bacterial adhesion to chalcopyrite. The extent of adsorption increased......
Controllable Protein Adsorption and Bacterial Adhesion on Polypyrrole Nanocone ArraysZhengnan Zhou1,2,Weiping Li1,2,Tianrui He1,2,Peng Yu1,2,Guoxin Tan3,Chengyun Ning1,21. School of Materials Science.... This film was expected to control protein adsorption and bacterial adhesion by potential-induced reversibly redox. The scanning Kelvin probe microscopy(SKPM) and surface contact angles(SCA) tests......

was 74.6 mg/g. The reason for the adsorption capacity difference may be that these two kinds of biosurfactants have different effects on cell surface charges of bacterial. RL is anionic surfactant...J. Cent. South Univ. (2012) 19: 1073-1080 DOI: 10.1007/s11771-012-1111-5 Effect of rhamnolipids on cadmium adsorption by Penicillium simplicissimum YUAN Xing-zhong(袁兴中)1, 2, JIANG Li-li(姜丽丽)1, 2......
parameters including the pH value, ferrous and ferric concentration, bacterial adsorption rate and copper leaching efficiency in the leaching solution were investigated. The results show that the ferric... of the chalcopyrite. Key words: chalcopyrite; jarosite; bioleaching; bacterial adsorption; hydrolysis 黄铜矿是重要的铜矿资源,约占世界铜矿资源的70%,也是开采最多的铜矿物.从黄铜矿中提炼铜的传统方法是火法冶炼,其具有生产效率高,铜回收率高等优点,但生产过程中产生大量SO2烟气严重污染环境.因此......
, Shenyang 110004, China) Abstract: The study on arsenopyrite and realgar of bacterial oxidation shows that the chemical behaviors of different arsenic-bearing sulphides oxidated by thermophilic bacteria...). Arsenopyrite is highly toxic to bacteria that at the initial stage of bio-oxidation, bacterial growth is inhibited and the number of bacterium cell drops from 2.26×108/mL to the lowest 2.01×105/mL......
ore, the sulfur content of sulfide minerals surface was reduced by bacteria desulfurization technology. Bacterial desulfurization experiments were carried out by using a novel strain of thermophile.... The desulfurization rate is 56.87% in the optimization experimental conditions, which is close to the predicted value, showing that regression result is good. Key words: bacterial desulfurization; response......
; Abstract: The adsorption mechanism of cysteine on pyrite was studied by amounts adsorbed, FTIR and XRD measurements. The results obtained by adsorption experiment suggest that as the mass ratio of mineral to cysteine mp/mc is greater than 5, the amounts adsorbed on mineral is stable after adsorption for 15 min and cysteine adsorbing with mp......
