A detailed study of precipitation reaction of perchlorate ion with tetraphenylarsonium chloride is reported. Optimum conditions for quantitative precipitation of perchlorate ion were determined. A gravimetric and a spectrophotometric method for perchlorate ion are proposed. The spectrophotometric method is based upon dissolution of (C6H5)4AsClO4 in acetonitrile and subsequent measurement of absorbance at 264 mμ. Results on selected samples prove both methods to be accurate and reproducible.
