In another aspect, a method of scrubbing ozone from a gaseous stream comprises contacting the gaseous stream with magnesium thiosulfate. In an alternative embodiment, chlorine is quenched from a water stream by contacting the stream with magnesium thiosulfate or potassium thiosulfate. In yet another aspect, a method of scrubbing chlorine from a gaseous stream comprises contacting the stream with magnesium thiosulfate or potassium thiosulfate.
