ALGAL GROWTH INHIBITORS AND USE THEREOF

摘要

An algal growth or microbial proliferation inhibitor, which contains, as an active component, at least one solid solution selected from the group consisting of the compounds of the formulae (1) to (4), the compounds of the formulae (1) to (4) being a hydroxide solid solution of the formula (1), Ä(M1<2+>)y(M2<2+>)1-yÜ 1-x M<3+>x(OH)2(A<n->)y/n . mH2O wherein y is a number in the range of 0 ≤ y ≤ 1, x is a number in the range of 0 < x ≤ 0.5, m is a number in the range of 0 ≤ m ≤ 2, M1<2+> is Zn<2+> and/or Cu<2+>, M2<2+> is Mg<2+> and/or Ca<2+>, M<3+> is at least one trivalent metal, and A<n-> is an anion of n valence, an oxide solid solution of the formula (2), Ä(M1<2+>)y(M2<2+>)1-yÜ 1-x M<3+>x-aO wherein y is a number in the range of 0 ≤ y ≤ 1, x is a number in the range of 0 < x ≤ 0.5, x-a means that the number of M<3+> is decreased by a due to a lattice defect, and M1<2+> and M2<2+> have the same meanings as those defined in the formula (1), a hydroxide solid solution of the formula (3), (M1<2+>)x(M2<2+>) 1-x (OH)2 wherein x is a number in the range of 0.0001 ≤ x < 0.9, and M1<2+> and M2<2+> have the same meanings as those defined in the formula (1), and an oxide solid solution of the formula (4), (M1<2+>)x(M2<2+>) 1-xO wherein x is a number of 0.0001 ≤ x < 0.9, and M1<2+> and M2<2+> have the same meanings as those defined in the formula (1), and an organic or inorganic material containing the inhibitor.
