如水体沉积物中的无机汞(Hg2+)在厌氧条件下，通过微生物的作用或在金枪鱼肝脏内，会转化为甲基汞。

The molecules involving azo and imino functional groups can coordinate with Hg2＋ to result in a large blue shift from 453 to 363 nm corresponding to a notable color change from orange to pale yellow in aqueous methanol solution (H2O/CH3OH＝1/4, V/V), which can be applied to naked eye detection of Hg2＋.

这些传感器分子包含偶氮和亚胺功能基团，在水/甲醇溶液（体积比1/4）中，可以与汞离子配位，使紫外-可见光谱中吸收峰发生由453到363 nm的蓝移，引起一个明显的溶液由橙色到淡黄的颜色变化。因而，这些传感器有肉眼检测汞离子的潜在应用。

Methods The conditions of solvent extracting active ingredient from pueraria lobata were optimized,and evaluating indIcators were contents of puerarin,lead and mercury, which were determined by high performance liquid chromatography and atomic fluorescence spectrometry.

方法采用高效液相色谱法和原子荧光光谱法测定葛根提取液中葛根素和铅、汞元素的含量，以葛根素和铅、汞元素的含量为评价指标，对影响溶剂回流提取葛根有效成分的条件进行优化。

In terms of the location of mining areas in Xiang-Qian mercury deposit belt as well as regional geology and paleogeographic setting.the genesis of country rocks is discussed.

梁仁枝，许效松，贵州丹寨寒武系层控型汞——金矿床研究由矿区在湘黔汞矿带所处的位置，结合区域地质及古地理背景，讨论了含矿围岩的成因。

The nickel, lead, cadmium and mercury ions were pre-column derived by tera-(2-aminophenyl)-porphine (T2APP). These chelates were enriched by solid phase extraction with C18 cartridge and the enrichment factor of 50 was achieved.

中草药样品用微波消化，样品消化液中的镍、铅、镉、汞用四－－卟啉(T2APP)柱前衍生，然后用ZORBAX RP18固相萃取小柱萃取富集镍、铅、镉、汞的T2-APP络合物，富集倍数为50倍；经富集后的络合物用乙腈和0.05mol？

Native gold presents in ultra finely grained and in thin schistose form.

采用重选、浮选和混汞的联合流程产出汞金、锑金精矿和白钨精矿三种产品。

Thus, the research on the mechanism and kinetics of such reaction has been a focus of understanding the influence of coal combustion on the air for scientists. In this paper, we put emphasis upon the reaction mechanism and kinetics of mercuric and stannic oxidation by oxidants. Up to date, the experiments showed that mercuric chloride species were the main products of mercuric oxidation, but the microscopic mechanism and kinetics of it were not well understood.

研究这些重金属元素在煤燃烧过程的化学反应机理及反应动力学特征，是目前研究煤燃烧对大气影响的重要的研究课题，本文中我们重点研究煤燃烧过程中汞和锡生成氧化物和氯化物的机理与反应动力学，煤燃烧过程实验发现汞系列产物主要是氯化物，但对其微观反应机理和反应动力学研究很少有报道。
