Abstract

A consistent analytical method incorporating sulfuric acid (H2SO4) digestion and ICP-MS quantification has been developed for TiO2 quantification in biotic and abiotic environmentally relevant matrices. Sample digestion in H2SO4 at 110°C provided consistent results without using hydrofluoric acid or microwave digestion. Analysis of seven replicate samples for four matrices on each of 3 days produced Ti recoveries of 97% ± 2.5%, 91 % ± 4.0%, 94% ± 1.8%, and 73 % ± 2.6% (mean ± standard deviation) from water, fish tissue, periphyton, and sediment, respectively. The method demonstrated consistent performance in analysis of water collected over a 1 month.
