Organic chloramines may be stable in the natural water body for a long time.Some organic chloramines show resistant to the sodium sulfite during the dechlorination. 有机氯胺在一定条件下可以在自然水体中长时间稳定存在,部分有机氯胺在脱氯时不易被亚硫酸钠脱除。
Sulfites or sulphites are compounds that contain the sulfite ion (or the sulfate(IV) ion, from its correct systematic name), SO2− 3. The sulfite ion is the conjugate base of bisulfite. Although its acid (sulfurous acid) is elusive, its salts are widely used.
