Abstract (en)
[origin: WO2017109521A1] The present invention refers to a method for the synthesis of an adsorbent which is realized by the production of a bivalent tin oxy-hydroxide [SnxOy(OH)z], with 1<x<6, 0<y<4 and 0<z<4, into a two-stage continuous flow reactor and a pH range 2-12. The material can be applied for the removal of hexavalent chromium, bromate, chlorate and perchlorate ions in drinking water treatment units for house, municipal and industrial use. The invention also relates to its adsorbent, resp. the use thereof.
