脱锌

A weak interaction between absorbent and adsorbate can be described well by counterpoise-method.

这种不同氧化锌晶体表面有相近的CO脱附热的现象是由于晶体表面存在固有的晶体缺陷-表面层阶梯造成的。

The results showed that the trace elements were not anomalously enriched. Zn and Cu existed in sphalerite. Cr, Pb and Cd were adsorbed by clay minerals. Ba might exist in ankerite and calcite. Ni, Mo, Co and As mainly existed in pyrite. Be and Se were combined with organics. Many trace elements were difficult to volatilize. Because of high content and volatility, Pb and Zn, are harmful to environments; Zn and Pb separately exist in sphalerite and clay minerals, so it is easy to reduce their environmental damage by washing and processing of coal.

结果表明：研究的元素没有异常富集；Zn和Cu赋存于闪锌矿中，Cr、Pb和Cd被粘土矿物吸附，Ba可能赋存于铁白云石和方解石中，Ni、Mo、Co和As主要赋存于黄铁矿中，Be和Se以有机结合态存在；研究的元素大多不易挥发，但Zn和Pb易挥发，且含量较高，环境危害较大，Zn和Pb分别赋存于闪锌矿和粘土矿物中，可通过洗选脱除减小其危害。

金霉素在冰醋酸与甲醇溶液中，用锌粉氢解，在温和条件下，产生脱二甲胺金霉素；较剧烈条件下，则生成脱二甲胺脱羟金霉素。

The results were as follows:Afterthe NH_4Y zeolite was dealuminated with Oxalic acid,the conversion of pinenespeeded up markedly, but the selectivity of camphene also dropped downmarkedly.After the NH_4Y zeolite was infused in solution of Mg(NO_3)_2,Zn(NO_3)_2 or Al(NO_3)_3 to remove corresponding oxide,the conversion rate of pinenedropped down,and the selectivity of camphene had little increase.

结果表明：NH_4Y型沸石分子筛经草酸脱铝后，蒎烯转化显著加快，但莰烯的选择性也显著下降；而NH_4Y型沸石分子筛经硝酸镁、硝酸(来源：caAB3aC论文网www.abclunwen.com)锌、硝酸铝溶液浸渍来负载相应的氧化物后，蒎烯转化率有所下降，莰烯选择性稍有增加。

The reductive dechlorination of trichloroethylene by surface-bound Fe in ZnO-Fe systems was studied by batch experiments.

通过批量实验研究了在氧化锌-Fe混合体系中，束缚在氧化锌表面的Fe对三氯乙烯的还原脱氯作用。

The experiments included both small and extended test. Because the Arsenic in secondary zinc oxide exists mainly in the form of arsenous oxide, which is volatile, the roasting method of adding reductant carbon to secondary zinc oxide is used to remove Arsenic.

本研究实验包括小型实验和扩大实验，由于次氧化锌中砷主要以三氧化二砷形态存在，因此可以通过三氧化二砷易挥发特性，采用在次氧化锌中加入炭还原剂的焙烧方法脱砷。

Composition of suspension will chang from titanium monoxide to titanium dioxide during standstill procedure. Experimental results show that the proposed method can successfully prepare the anatase phase of titanium dioxide .In the photocatalysis experiment, the prepared titanium dioxide nanofluid absorbs the Ultraviolet when light wavelength was 360 to 380 nm. Adsorption experimental results show that the efficiency of absorbing methylene blue using TiO2 is higher than that for TiO2 (Degussa P-25) or ZnO. Depigmentation of methylene blue experimental using TiO2 can depigmentize methylene blue reach 100% in 60 min.

悬浮液所含之奈米颗粒在静置过程中，成份方面会由似一氧化钛转变为二氧化钛；在结晶组成方面，所制备之二氧化钛颗粒之结晶组成为锐钛矿结构；在光催化方面，所制备之奈米二氧化钛悬浮液在光波长360nm~380nm时产生吸收紫外光现象，在吸附实验中本制程所制备的二氧化钛颗粒的吸附效果优於商用的二氧化钛及氧化锌，在亚甲基蓝的脱色实验中本制程所制备的二氧化钛颗粒能在60分钟内达到脱色率100%。

Phenolic resin/montmorillonite hybrid resin were prepared by Zn_2 catalyst and cured by p-toluene sulphonic acid through one step process in this paper.

在醋酸锌催化剂作用下，采用边缩聚边插层的一步法制备了酚醛树脂/蒙脱土杂化树脂，并采用对甲苯磺酸为室温固化剂制得酚醛树脂/蒙脱土复合材料。

Mesoporous zincum sulfide is synthesized by gentle wet chemosynthesis method, with DDA as templates and Zinc acetate and TAA as precursors. The effect to the synthesis of the ratio of reactive components, the volume of pH, reactive time and reactive temperature has been dicussed systematically, and structures of the as-synthesized samples have been characterized by X-ray diffraction, N2 adsorption-desorption, scanning electron microscopy, Fourier transform-infrared spectra, UV-vis diffuse reflectance spectroscopy, transmission electron microscopy.

以十二胺为模板，醋酸锌及硫代乙酰胺为前驱体，温和湿化学法合成了硫化锌无序介孔结构，系统研究了反应物配比、pH值、反应温度、反应时间对材料合成的影响，运用X射线衍射、N2吸附-脱附、扫描电镜、红外光谱、紫外-可见吸收光谱、透射电镜等分析手段对介孔材料的结构进行了详细的表征。

本文在前文基础上，用旋转圆盘-圆环电极进一步研究了两相黄铜HPb59-1在不含Cu~+的去氧酸性氯化钠溶液中阳极溶解时的脱锌行为。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
