degradation of etfose and mefose results in the formation of pfos anion and pfoa.
乙基全氟辛基磺酰氨基乙醇和甲基全氟辛基磺酰氨基乙醇降解后会形成全氟辛烷磺酸阴离子和全氟辛酸。

the unintended risk which led to a ban of the pesticide was also due to the anion.
导致禁止这种农药的意外的风险也是由于负离子引起的。

the original swedish nomination included 96 substances in addition to the perfluorooctane sulfonate anion.
除全氟辛烷磺酸阴离子外，瑞典的最初提名包含96种物质。

a loss of organic anion accumulation at the higher dose was earlier and greater in female rats.
在较高剂量下，雌性大鼠体内较先出现有机阴离子积累量减少的情况，且幅度较大。

it should be stated which anion is resent (e.g. paraquat dichloride).
必须指出会与哪种阴离子产 生反应（如百草枯二氯化物）。

this would be based on the reasonable assumption that all salts are ionized and dissociate in the environment to liberate the anion.
这种办法所依据的合理假定是：所有的盐类都是离子化的，游离于环境中并释放阴离子。

the perfluorooctane sulphonate anion (pfos) did not have a specific cas number when the notifications were submitted.
提交报告时，全氟辛烷磺酸阴离子并没有特定的化学文摘社编号。

even for very insoluble salts there would be an equilibrium concentration of free pfos anion that could be attached to more soluble cation and be available for biota.
即使是极难溶解的盐类，也会有均衡浓度的游离全氟辛烷磺酸阴离子附着到较易溶解的阳离子上或出现于生物区中。

163. the cation exchange membrane and anion exchange membrane were found to respond differently over a range of ph of catholyte and anolyte, respectively.
163. 发现了阳离子交换膜和阴离子交换膜，分别对应阴极电解液和阳极电解液的不同ph值。

pfos, as an anion, does not have a specific cas number. the parent sulfonic acid and some of its commercially important salts are listed below:
全氟辛烷磺酸，作为一种阴离子，没有专门的化学品文摘社编号，其同源磺酸和一些具有重要商业用途的盐类如下所列：

perfluorooctane sulfonate (pfos) is a fully fluorinated anion, which is commonly used as a salt in some applications or incorporated into larger polymers.
全氟辛烷磺酸是完全氟化的阴离子，以盐的形式广泛用于某些用途或并入较大的聚合物。

on the closely-related issue of salts of proposed chemicals, pfos and its salts are normally dissociated in aqueous solutions and in terrestrial and aqueous organisms into the cation and the pfos anion.
9. 就密切相关的拟议化学品的盐类问题而言，全氟辛烷磺酸及其盐类在水溶液和在陆地和水中生物中通常分离成正离子和全氟辛烷磺酸负离子。

noting that the perfluorooctane sulfonate anion does not have a chemical abstracts service number and does not appear as an anion in the environment, but that the perfluorooctane sulfonate acid and its salts listed in the proposal have the following chemical abstracts service numbers:
注意到 没有为全氟辛烷磺酸的阴离子设置任何化学文摘社编号、而且此种化合物在环境中并非以一种阴离子形式出现，而在相关提案中所列出的全氟辛烷磺酸及其各种盐类则已有化学品文摘社编号如下：

metal ions were analyzed using inductively coupled plasma-optical emission spectrometry (icp-oes) and anion analyses were conducted using ion chromatography.
用电感耦合等离子发射光谱(icp-oes法)对金属离子进行了分析，还用离子色谱法进行了阴离子分析。

cas number 45298-90-6 has recently been listed on some chemical databases as that for the pfos anion (1-octanesulfonic acid, 1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-heptadecafluoro-, ion(1-)).
最近已将45298-90-6作为它（1,1,2,2,3,3,4,4,5,5,6,6,7,7,8,8,8-十七氟-1-辛烷磺酸，阴离子(1-)）的化学文摘社编号，列入某些化学品数据库中。
