NEW HYBRID BIODEGRADABLE POLYMER FOR EFFICIENT NITROGEN AND PHOSPHATE REDUCTION

摘要

The invention relates to a biodegradable polymer that is coupled to metal-(OH/CO3)n beads (hybrid POL/metal-(OH/CO3)n). The invention further relates to a container and a filtering agent comprising the hybrid POL/metal-(OH/CO3)n, and to the use of methods of hybrid POL/metal-(OH/CO3)n for reducing nitrogen compounds from an aqueous solution.

1. A filtering agent for water filters comprising a biodegradable polymer that is mixed with metal-(OH/CO3)n beads (hybrid POL/metal-(OH/CO3)n), whereby the polymer is selected from the group consisting of polycaprolactone, polylactic acid, poly(lactic-co-glycolic acid), a polyhydroxy alkanoate-type polymer, a natural polymer and poly(3-hydroxypropionic acid) (P(3-HP), or a mixture of at least two of said polymers, and whereby the metal-(OH/CO3)n is selected from the group consisting of Fe(OH)3, Fe2O3, Al(OH)3, Al2(CO3)3, and La(OH)3.
