草酸盐

Could be used as an efficient biosorbent for removal of heavy metal ions from aqueous solution and that the process was strongly affected by pH.

研究发现，溶液pH值对吸附过程有较大影响，最佳吸附pH值在5.5附近；最佳吸附温度为25～35℃；溶液浓度在10～500mg·L^-1范围内，固定化简青霉菌对重金属的吸附随金属离子浓度的增加而增加；吸附过程符合Langmuir等温吸附模型；生物吸附平衡时间约为60min。

Although the minutes of cabinet meetings do not identify individuals, they are by convention kept private for fear that ministers might otherwise censor themselves, or that minuted decision-making might give way to informal discussions elsewhere.

尽管内阁会议备忘录没有指明个人的身份，它们通常会被私下封存好，因为有人担心可能导致大臣们自我监督，或者那样的记载的决策可能会为在别处的非正式讨论让步。
