主题：ICP-AES系列学习12.13:Problem Elements

好东西,先顶一下 ,明天再看.要是有人翻译出来就好了

顶下先,再慢慢看

被顶上来了，请英语翻译版主过来帮帮忙！

呵呵，量有些大，建议设为悬赏帖，鼓励有能力有闲的人翻译

10.Barium (Ba)
10.钡 
Of the four acids most commonly used in sample preparations,
四酸经常用于处理样品。
Ba will form precipitates with HF and H2SO4.
钡会和HF、H2SO4形成沉淀。
In addition, the solubility of BaHPO4 and BaCrO4 are 0.01 and 0.001 g/100 g H2O respectively.
另外，BaHPO4、BaCrO4在水中的溶解度分别是0.01 、 0.001 g/100 g H2O
Solutions that are neutral or alkaline will ppt. BaCO3 (solubility 0.0024 g/100g H2O).
在中性和碱性溶液中将会形成BaCO3沉淀，（溶解度为0.0024 g/100g H2O）
Samples containing Ba and sulfur compounds may form BaSO4 in oxidative decompositions.
钡和硫元素在氧化性溶液中会形成BaSO4沉淀。
I know of no simple way to dissolve this precipitate.
据我所知，还没有一个简单的方法可以将BaSO4沉淀溶解。
Since small amounts of barium sulfate do not readily coagulate the precipitate can easily go unnoticed.
少量的硫酸钡沉淀凝聚缓慢，往往被忽略。
Attempts to dissolve barium sulfate have seemingly focused upon the use of EDTA (Kf 7.86) and DTPA (Kf 8.78).
硫酸钡沉淀的溶解主要是用EDTA (Kf 7.86) 和 DTPA (Kf 8.78).
However, the pH of the solution, which must be ~ 5, can lead to precipitation and/or adsorption problems with other analytes and the dissolution rate is slow.
然而，溶液的pH值必须在5左右，这将导致溶液中其它待测组分析出沉淀或形成吸附，而且溶解的速度很慢。

Avoid combinations of Ba+2 with SO4=, CrO4= or F-1 in acidic media.
在酸性介质中避免钡离子同硫酸根、铬酸根、氟离子相遇。

Avoid raising the pH of sample solutions containing Ba+2 to 7 or greater to avoid loss as the carbonate or hydrogen phosphate
避免使溶液的pH值等于或大于7，以免钡离子以碳酸盐或磷酸氢盐的形式损失。


呵呵，找了个短一点的翻译了一下，不知道对不对，请高手斧正。

俺也来试一段：
2.Gold (Au)
The chemical stability of Au is very similar to that of Hg. The following suggestions may be helpful:
Nitric acid solutions of Au at the low ppm and ppb levels are not stable. Use HCl matrices.
Do no use Pt crucibles when ashing samples containing Au. Au will alloy with the Pt.
When measuring Au in the presence of significantly greater amounts of Pt using ICP-MS, be aware of the resolving capability of your instrument.
金（Au）
Au和Hg的化学稳定性非常相似。以下的建议也许有用：
Au的硝酸溶液在低的ppm和ppb级的水平下是不稳定的。使用HCl基体。
当灰分样品含有Au的时候不要使用Pt坩锅。Au将和这些Pt融为合金。
在Pt更大量存在下使用ICP-MS的时候测定Au，注意你的仪器的溶解性能。

再来一段：
5.Sodium (Na)
The single most common problem with Na is contamination. Sodium is literally everywhere. Thousands of tons of salt are transferred from the ocean to the air in the form of sub-micron particulates and can travel for hundreds of miles inland. For more information on contamination please refer to the following links:
Environmental Contamination
Contamination From Reagents
Contamination From the Analyst and Apparatus
5.钠（Na）
使用Na一个最普遍的难题是污染。Na是无处不在。成千上百吨的盐以亚微米颗粒的形式从海洋转变到空气中，并且能够在内陆传播几百英里。关于污染的更多信息请参考以下链接：
环境污染
溶剂污染
分析物及装置污染

“注意你的仪器的溶解性能”是什么意思呢？不明白，没用过ICP-MS。

嘿嘿，不好意思，俺对这也不是很熟悉，估计翻译错误， 好像应该是“仪器的分辨能力”

都没人继续翻译了……，
