摘要:
Method for solubilizing tellurium over a wide pH range using a-substituted carboxylic acids as solubilizing agents. Particular examples of solubilizing agents include hydroxyacetic acid, tannic acid, tartaric acid, citric acid, 2,6-pyridine dicarboxylic acid, lactic acid, gluconos-lactone (gluconic acid), 2-puroic acid, thiophene-2-carboxylic acid, 2,3-pyridine dicarboxylic acid, phosphonoacetic acid, thiophene-2-acetic acid and mercaptoacetic acid. Related compositions containing soluble tellurium are also disclosed.
