Optimization of the Nonaqueous Capillary Electrophoresis Separation of Metal Ions Using Mixture Design and Response Surface Methods
Nonaqueous capillary electrophoresis metal ions mixture design response surface methods
2010/4/19
Mixture experimental design was used to enhance the separation selectivity of metal ions in nonaqueous capillary electrophoresis. The separation of cations (Ag, Fe, Cr, Mn, Cd, Co, Pb, Ni, Zn and Cu) ...
pH值和金属离子对尖吻蝮蛇抗凝血因子Ⅱ二级结构的影响（The Effects of pH and Metal Ions on the Secondary Structure of Anticogulation Factor Ⅱ Studed by CD Spectroscopy）
抗凝血因子Ⅱ 酸度(pH) 二级结构 圆二色谱
2010/8/25
圆二色谱(CD谱)测量表明，尖吻蝮蛇抗凝血因子Ⅱ(ACF Ⅱ)与抗凝血因子Ⅰ(ACF Ⅰ)的二级结构十分相似，它们的主要骨架构象都为反平行β-折叠和α-螺旋结构。pH值对天然ACF Ⅱ的构象有一定的影响，pH值从3到10增大时，α-螺旋含量逐渐减少，反平行β-折叠含量逐渐增大。钙和其他二价金属离子对ACF Ⅱ的骨架结构没有明显影响。三价稀土离子使ACF Ⅱ的α-螺旋含量升高，同时降低其β-转角和β...
Determination of Selenium(IV) Using o-Phenylenediamine by Differential Pulse Polarography/Interference of Metal Ions
Selenium determination o-phenylenediamine Interference's problem Polarography
2010/4/20
A new sensitive and selective pulse polarographic method for the determination of Se(IV) next to interfering ions is described. This method is based on the highly sensitive peak formed by the reactio...
New Adsorbents from Ti(OPrn)4 by the Sol-Gel Process: Synthesis, Characterization and Application for Removing Some Heavy Metal Ions from Aqueous Solution
Sol-gel process adsorption adsorbent waste water heavy metals coating
2010/4/21

The Influence of Transition Metal Ions the Kinetics of Ascorbic Acid Oxidation Methylene Blue
2010/4/22
The kinetics of the oxidation of L-ascorbic acid (H2 A) by methylene blue was investigated in strongly acidic media over the temperature range 22-40 oC. The kinetic studies were carried out as a funct...
Adsorption of Some Heavy Metal Ions from Aqueous Solution by Activated Carbon and Comparison of Percent Adsorption Results of Activated Carbon with those of Some Other Adsorbents
Heavy metal adsorption activated carbon chitosan agar adsorption from aqueous solution adsorption kinetics adsorption isotherm
2010/6/27
In this study, removal of some heavy metals ions (Mn2+, Fe2+, Ni2+ and Cu2+) from aqueous solution by adsorption was investigated. For this purpose, high-grade MnSO4.H2O, FeSO4.7H2O, NiSO4.7H2O and Cu...
