以下为一段使用英文,希望有高手帮忙翻译下,因为我翻译了,总感觉好象有理解不通的地方。谢谢。!!

Polymers
======================
Ba(barium)
--------------------
Typical range
0-0.1%
-----------------
Interferences

Barium is partially ionized in the nitrous oxide-acetylene flame. To suppress ionization add potassium chloride to give a final concentration of 5000ug/ml potassium in solution.
-------------------------

Sample preparation

Refer to preparation recommended for cadmium in polymers.
----------------------------

Standard preparation
Two sets of calibration standards are required for this determination:
a)0-40ug/ml Ba in dilute H2SO4(硫酸)
b)0-40ug/ml Ba in EDTA/NaOH solution.
Add 5000ug/ml potassium as ionization suppressant to the acid solutions.
Presence of sodium from NaOH will suppress the ionization of barium in the second set of solutions.
Concentrations of reagents and major matrix components in both sets should be matched.

Interferences 干扰
Barium is partially ionized in the nitrous oxide-acetylene flame. To suppress ionization add potassium chloride to give a final concentration of 5000ug/ml potassium in solution.
钡在氮氧化物-乙炔火焰中部分地被电离。加氯化钠来使溶液中钠的最终浓度达到5000ug/ml以抑制离子化
Sample preparation 样品制备
Refer to preparation recommended for cadmium in polymers. 参考推荐的聚合物中镉的制备方法。
Standard preparation 标准制备
Two sets of calibration standards are required for this determination:
需要两个校准溶液来进行检测
a)0-40ug/ml Ba in dilute H2SO4(硫酸) a) 含0-40ug/ml 钡的稀硫酸
b)0-40ug/ml Ba in EDTA/NaOH solution. b) 含0-40ug/ml 钡的乙二铵四乙酸/氢氧化钠溶液
Add 5000ug/ml potassium as ionization suppressant to the acid solutions.
在酸溶液中5000ug/ml钾来作为离子化抑制剂。
Presence of sodium from NaOH will suppress the ionization of barium in the second set of solutions.
氢氧化钠中钠的存在可以抑制第二个校准溶液中钡的离子化
Concentrations of reagents and major matrix components in both sets should be
matched.
两个校准溶液中试剂的浓度和主要基质的组成要相称。

Sample preparation
Weigh accurately 2.000 g of polymer cut into small pieces and place in a 200mL conical flask. Slowly add 10mL of concentrated sulfuric acid, cover with a watch glass and heat until charring is well progressed. Allow to col and add, dropwise, sufficient hydrogen peroxide(100 vols) to oxidize the charred matter and heat again. Cool, and repeat addition of hydrogen peroxide until solution remains colorless. Heat to white fumes of sulfuric acid, but do not try to greatly reduce the acid volume.
If solution is clear, add 20 mL of distilled water to the cool digestion mixture and transfer to a 100mL volumetric flask and make up to volume. The solution prepared from a sample with 0.01% Cd will contain 2ug/mL Cd.
For digestion with precipitate follow an alternative procedure.
Cool the digestion mixture and add 20mL of distilled water. Swirl for ten minutes, cool and filter through a Whatman 42 paper.
1.Acid solution
Wash the precipitate with distilled water collecting the filtrate and the subsequent washings in a 100mL volumetric flask. Make up to volume with distilled water.
2.Alkaline solution
Place the funnel with the filter paper and the precipitate in the neck of a 50mL volumetric flask. Dissolve the precipitate by washing the paper with 20% sodium hydroxide solution saturated with EDTA. Follow by distilled water washing and make up to volume.

样品制备
准确称量2g聚合物,切成碎片,然后置于200ml锥形瓶中。缓慢加入10ml浓硫酸,盖上表面皿,加热烧成灰。冷却后,加入足够的双氧水使灰化物被氧化,然后再次加热。冷却后,重复加双氧水,直至溶液变为无色。加热至硫酸冒白烟,注意不要使硫酸体积损失太多。
如果溶液澄清,向消解产物中加20ml蒸馏水,并转移至100ml的容量瓶中定容。这样由含0.01%Cd的样品配备的镉溶液的浓度是2ug/mL。
如果消解过程中产生沉淀,采取如下措施。冷却消解液,添加20ml蒸馏水,搅拌十分钟,冷却后,使用Whatman 42纸进行过滤。
1。酸溶液
使用蒸馏水清洗沉淀物,收集滤液至100ml容量瓶。使用蒸馏水定容。
2。碱溶液
在漏斗上铺上滤纸,将沉淀物置于漏斗中后,置于50ml容量瓶中,使用EDTA饱和的20%的氢氧化钠溶液清洗,然后使用蒸馏水清洗并定容。

感谢楼上的帮忙。

思考了下,感觉这个仪器给的方法好象有点怪诶。
因为要是实际操作中,如果把10浓硫酸和塑料给烧成灰恐怕有点困难啊。

这个和EN1122的方法相似,但是EN1122里只是说烧到冒白烟在烧15分钟。
好象没有烧成灰的。不知道有没有人做过此类的实验啊。

这样说,如果没有沉淀那么就不需要后面的两个步骤了。
