Abstract

"SOLUçãO AQUOSA DE SAL DE CROMO E MéTODO PARA PRODUçãO DA MESMA". é apresentada uma solução aquosa de sal de cromo, na qual o conteúdo de ácido oxálico é de 8% ou menos com relação ao cromo. Na solução aquosa do sal de cromo, o conteúdo total de carbono orgânico é de 4% em peso ou menos com relação ao cromo. O sal de cromo é preferencialmente um cloreto de cromo, um fosfato de cromo, ou um nitrato de cromo. O cloreto de cromo preferencialmente contém um cloreto básico de cromo representado pela fórmula de composição Cr(OH)~ x~Cl~ y~ (onde O < x <243> 2, 1 <243> y < 3, e x + y = 3). O fosfato de cromo é preferencialmente um representado pela fórmula de composição Cr(H~ 3-3/n~PO~ 4~)~ n~ (onde n é um número satisfazendo 2 <243> n <243> 3). O nitrato de cromo é preferencialmente um representado pela fórmula de composição Cr(OH)~ x~(NO~ 3~)~ y~ (onde O < x <243> 2, 1 <243> y < 3, e x + y = 3).
