摘要

The aluminum dissolved forms have been investigated in the water of the Kiev reservoir. The main part of aluminum belongs to organic complex compounds with a relatively low molecular weight (up to 5000 a.m.u.). The humic substances play the priority role in the process of the complex formation. The carbohydrates are the second group of potential organic ligands. The protein-like substances bind the least quantity of aluminum. The seasonal distribution of aluminum between its complex compounds with dissolved organic substances is shown.
