Abstract

Esta solicitud se refiere a un proceso para producir un reactivo de tipo fosfato cálcico, según el cual: - en un primer paso, se utiliza una fuente de calcio y una fuente de iones fosfato en agua con una relación molar que se ajusta de modo que se obtenga una relación molar de Ca/P comprendida entre 0.5 y 1.6, y la fuente de calcio se hace reaccionar con los iones fosfato a un pH comprendido entre 2 y 8, con el fin de obtener una suspensión (A) de fosfato cálcico, y - en un segundo paso, se añaden a la suspensión (A) un compuesto alcalino que comprende iones hidróxido con el fin de establecer un pH superior a 8 y una fuente adicional de calcio con el fin de obtener una suspensión (B) del reactivo de tipo fosfato cálcico con una relación molar de Ca/P superior a 1.6. Además, la solicitud se refiere a un método para purificar un efluente líquido que contiene elementos metálicos y/o elementos no metálicos con el reactivo de tipo fosfato cálcico que se puede obtener según este proceso.
