From popular culture to basic science, water and its solutions feature prominently. Indeed, our fascination with water ranges from epic films chronicling the devastating impact of tidal waves and floo...
Abstract: The mass-dependent equilibrium stable isotope fractionation between different materials is an important geochemical process. Here we present an efficient method to compute the isotope fracti...

A series of starch-g-poly(acrylic acid)/sodium humate (St-g-PAA/SH) hydrogels were prepared and used to adsorb Cu2+ from the aqueous solution. The batch adsorption experiments were carried out by vary...
The sorption of Co(II) on Na-attapulgite as a function of contact time, solid content, pH, ionic strength, foreign ions, fulvic acid (FA) and temperature under ambient conditions was studied. The kine...
In order to improve the adsorption capacity of chitosan (CTS) for methylene blue (MB) cationic dye, a series of N,O-carboxymethyl-chitosans (N,O-CMCTS) were prepared under heterogeneous conditions by ...
An ultra-sensitive and highly selective non-extractive spectrophotometric method is presented for the rapid determination of iron(II) at trace levels using 2', 3, 4', 5, 7-Pentahydroxyflavone (morin) ...
摘要 By using spectrophotometric and potentiometric techniques the formation constants of the species formed in the systems H++Mo(VI)+nitrilotriacetic acid and H++nitrilotriacetic acid have been determi...

专著信息 书名 Electrochemical study on the keto-enol tautomerization of p-hydroxyphenylpyruvic acid in aqueous solutions 语种 英文 撰写或编译 作者 Yuwu Chi,Jianping Duan,Xiuzhen Qi,Guonan Chen 第一作者单位 出版社 Bioelectroche...
A commercial active carbon was tested as an adsorbent for the removal of phenol from aqueous solutions. The optimum conditions for maximum adsorption in terms of shaking time, amount of the adsorbent,...
The mechanism and kinetics of the reaction between aqueous solutions of COS and a sterically hindered primary amine, 2-amino-2-methyl-1,3-propanediol (AMPD), were investigated at 288-303 K using a sto...
Abstract: Three methods were developed that allow for the imaging of any clay mineral in aqueous solutions with atomic force microscopy (AFM). The methods involve fixing the particles onto special sub...
Abstract: The ability of Na-activated bentonite to remove Ni2+ and Co2+ from aqueous solutions at room temperature (22 ± 1°C) was studied under various experimental conditions. The parameters studied ...
Hydrolyzed polyacrylamide gels immersed in aqueous solutions of poly(ethylene glycol) (PEG) of molecular weight 300 exhibit a discontinuous volume change upon continuous increase of the PEG concentrat...
