Finally, refineries emit many gases like sulphur dioxide (SO2), nitrogen oxide (NO2), carbon dioxide, carbon monoxide, methane, dioxins, hydrogen fluoride, chlorine, benzene and others.

最后，炼油厂排放很多的气体，如二氧化硫(SO2)、二氧化氮(NO2)、二氧化碳、一氧化碳、甲烷、双环氧乙烷、氟化氢、氯、苯和其他气体。

Conceal disturbing elements like iron, copper, lead with hydrogen fluoride amine-EDTA, add the potassium iodide to separate iodine, and take starch as indicator, titrate with sodium hyposulfite.

试样以王水分解、泡塑富集分离金，硫脲解脱，以硝酸-硫酸破坏硫脲，用氟化氢胺- EDTA掩蔽铁、铜、铅等干扰元素，加碘化钾使之析出碘，以淀粉为指示剂，用硫代硫酸钠进行滴定。

Yes I have seen the advocacy for Liquid Fluoride Thorium reactors and there are some apparent tantalizing advantages over current Uranium reactor designs like ability to burn plutonium as a starter fuel, less production of transuranics, higher fuel burn efficiencies, etc.
