Popis:	A robust autonomous system is described for the spectrophotometric determination of aqueous elemental iodine in multiple flowing process streams. The quantitative methodology uses characteristic absorbance at 460 urn, corrected for baseline drift using absorbance at 600 nm. Linear dynamic ranges of 0.2 - 25 mgIL, 0.4 - 45 mgIL, and 2 - 250 mgIL have been attained using path lengths of 1 em, 5 em, and 10 em respectively. The multiplexed iodine monitor has proven capable of continuous operation for periods of up to eighteen months.
