| Abstract: | Abstract A novel spectrophotometric method for the determination of titanium(IV) by using a new reagent, water extract of slippery elm leaf is developed. In 0.05 M hydrochloric acid, titanium(IV) reacts with this reagent to form a yellow product. The formed product shows maximum absorbance at 415 nm with a molar absorptivity value of 0.68×104 l mol–1 cm–1 and the method was linear in the 0.2–6 µg ml?1 concentration range. The detection limit value was found to be 0.0131 µg ml?1. The proposed method was simple, low cost, selective, and sensitive. It was applied to the analytic samples with satisfactory results. |
