- Department of Chemistry, Jawahar Bharati, Kavali-524 202 Manuscript received 17 November 1977, revised 2 March 1981, accepted 30 May 1984 Oxytetracycline hydrochloride, Terramycin, is introduced as a new reagent for the spectrophotometric determination of trace quantities of boron in concentrated sulphuric acid medium. The reagent has an absorption maximum at 430 nm, and that of the boron complex at 520 nm. The coloured system conformed to Beer's law between 2 and 10 \(\mu\)g of boron at 520 nm. The molar absorptivity calculated on the basis of boron is 10,800 I mol-1 cm-1. The composition of the complex has been shown to be 1 : 1 both by the slope ratio and molar ratio methods.
