Method of producing agent for removing dissolved phosphorus compounds from water and agent for removing dissolved phosphorus compounds from water

摘要

A method for the producing of an agent for the removal of dissolved phosphorus compounds from water, according to the present invention, relying on the formation of the biopolymer metal compound system which is characterized by that, the natural plant fibres are subjected to the activation, subsequently the activated natural plant fibres are coated with biopolymer or derivatives thereof with the ionic character. The natural plant fibres are coated with at least one water-soluble polyvalent metal compound before or after coating the natural plant fibres with biopolymer or derivatives thereof with the ionic character. Such modified natural plant fibres are then rinsed and dried to obtain a composite fibrous material in the form of biopolymer hydrogel support crosslinked in the presence of water-soluble polyvalent metal compound support on the warp from natural fibre. An agent for the removal of dissolved phosphorus compounds from water, according to the present invention, containing the biopolymer and metal compounds which is characterized by that, said agent has the form of composite fibrous material, which are the hydrogel supports on the warp from natural fibre, wherein the hydrogel support constitutes biopolymer or derivatives thereof with the ionic character crosslinked in the presence of at least one water-soluble polyvalent metal compound.
