Essay

The thesis is devoted to research of coexisting forms of Al (III) and its distribution among abiotic components of various type surface water bodies. It is established, that ratio of suspended and dissolved forms of Al (III) depends on the content and nature of suspended matter as well as component composition and concentration of the dissolved organic matter. Among Al (III) dissolved forms complexes with fulvic acids with molecular weight about 2,0 kDa are prevailed. Maximal binding of Al (III) by humic substances is reached at water pH 4,0-6,0. The most migration of Al (III) from bottom sediments occurs at decrease of water рН and increase of fulvic acid concentration.
