铬

Various chrome complex dyes(1:1 ratio) of mordant black 1,mordant black 7,mordant black 9 and mordant black 11 have been synthesized and sodium dichromate is been used as mordant agents instead of Cr3+ to oxidate dyes sufficiently.

还设计合成了媒介黑1、媒介黑7、媒介黑9和媒介黑11的高水溶性1∶1络合染料，重铬酸钠作为铬化试剂，染料得到了充分的氧化，无色配体多羟基羧基酸的引入使染料有很好的水溶性，该实验路线未见报道。

The peak currents i p and peak potentials E p of the oxidation peaks for sodium dichromate solution of different concentrations, i.e ., water under the existence of sodium dichromate, were experimentally measured at different temperatures and sweep rates v on the electrode.

实验测得不同温度、不同扫描速度 v 、不同浓度重铬酸钠溶液即重铬酸钠存在下水在电极上的氧化峰峰电流ip和峰电位Ep，建立了 i p～ v 1/2和 E p～ln v 方程，表明电极反应是主要受扩散控制的不可逆反应。

The competition research showed that HT was prefer to sorb phosphate than chromate. Sorb of chromate on HT decreased with increasing phosphate.

竞争实验结果显示HT溶液中含有少量磷酸根离子即可抑制铬酸根离子在HT上之吸附，但铬酸根离子对磷酸根离子之吸附影响并不大。

This method is fast,accurate,simple and is used to the routine check of the metallic iron in sponge iron with satisfactory result.

介绍了用三氯化铁-重铬酸钾容量法测定海绵铁中金属铁的方法，试样用三氯化铁溶液选择性地使金属铁溶解，过滤分离不溶物，移取部分滤液，用重铬酸钾容量法直接滴定，方法快速准确，操作简便，用于海绵铁中金属铁的日常检测，可获得满意结果。

The XPS shows the content of chromium will increase with increasing chromium sputter gun power.

XPS中发现，铬含量会随著铬电子枪参数的增加而增加。

The maximal absorption wavelength of chromium with the DPC colored complex and internal standard is 540 nm and 440 nm, respectively.

铬与DPC显色铬合物和内标物的最大吸收波长分别为540nm和440nm，校正后的ACr440值与Cr含量之间呈良好的线性关系，相关系数为0.9997。

Hi a long time in the future, chrome tannage is still the most important tanning method.

在各种鞣剂中，鞣制效果最好的当属铬鞣剂，它有着其它鞣剂无法比拟的优越性能，在相当长的一段时间内，铬鞣法仍然是最主要的鞣制方法。

To solve this problem,one of the routes with good potential for success is to treat collagen with special modifier to implement high exhaustion chrome tannage by simply providing additional cross-linking sites or binding sites for chromium.

解决这一问题的一条有效途径就是在铬鞣前采用改性剂对胶原进行改性，通过给胶原分子上引入附加交联点和结合点以实现高吸收铬鞣。

The removal of heavy metal chromium from tannery sludge by bioleaching technology was reported in this paper.

比较研究了皮革废水处理厂的剩余污泥在生物淋滤除铬过程中，由于添加辅助基质的种类、浓度及反应温度不同，重金属铬溶出效果的差异。
