Method of forming co-precipitated material

Claim 1

A METHOD OF FORMING AN IMPROVED MATERIAL HAVING A MATRIX INCLUDING OXIDIZED, UNIFORMLY DISPERSED ACTIVE AND CARRIER MATERIALS SO AS TO BEUSEFUL, NOT ONLY AS A CATALYST, BUT ALSO AS AN ADSORBENT TO ADSORB FROM A LIQUID A HIGH CONCENTRATION OF CONTAMINANTS SELECTED FROM THE GROUP CONSISTING OF ARSENIC AND SELENIUM DEEPLY WITHIN ITS MATRIX AND RETAIN ITS STRUTURAL INTEGRIITY COMPRISING THE STEPS OF: A. PREPARING A FIRST SINGLE AQUEOUS SOLUTION CONTAINING UNIFORMLY DISTRIBUTED THROUGHOUT DISSOLVED WATER-SOLUBLE SALTS XM AND YM OF AN ACTIVE CATION AN OF A CARRIER CATION, RESPECTIVELY: WHERE X IS A CATION OF AN ACTIVE MATERIA AND IS SELECTED FROM THE GROUP CONSISTING OF IRON AND COBALT, WHERE Y IS A CATION OF A STRUCTURALLY ADEQUATE CARRIER FORMING A HIGH SURFACE AREA MATERIAL AND IS ALUMINUM, AND WHERE M IS AN ANION OF A WATER-SOLUBLE SALT OF X AND Y AD IS SELECTED FROM THE GROUP CONSISTING OF NITRTE AND HALIDE, B. REACTING SAID DISSOLVED SALTS IN SAID FIRST SINGLE AQUEOUS SOLUTION WITH A BASIC ZN IN AQUEOUS SOLUTION TO FORM INSOLUBLE CO-PRECIPITATES XN AN YN AND A BY-PRODUCT ZM, SAID ZN BEING PRESENT IN AN AMOUNT GREATER THAN THE STOICHIOMETRIC AMOUNT REQUIRED FOR COMPLETE REACTION IN ORDER TO FORM UNIFORMLY DISPERSED INSOLUBLE CO-PRECIPITATES: WHERE Z IS A CATION FORMING A WATER-SOLUBLE BASIC MATERIAL WITH N AND FORMING A REACTION PRODUCT WITH THE ANION M THAT CAN BE READILY REMOVED FROM SAID INSOLUBLE CO-PRECIPITATES, AND WHERE N IS AN ANION FORMING A WATER-SOLUBLE BASIC MATERIAL WIH Z AND FORMINGINSOLUBLE CO-PRECIPITATES WITH X AND Y AND IS SELECTED FROM THE GROUP CONSISTING OF CARBONATE AND HYDROXIDE, C. DRYING SAID UNIFORMLY DISPERSED CO-PRECIPITATES TO REMOVE THE WATER THEREFROM, D. REMOVING SAID BY-PRODUCT FROM SAID UNIFORMLY DISPERSED CO-PRECIPITATES, E. COMMINUTING THE DRIED UNIFORMLY DISPERSED CO-PRECIPITATES, F. FORMING THE COMMINUTED UNIFORMLY DISPERSED CO-PRECIPITATES INT AN AQUEOUS SLURRY, G. FORMING SAID SLURRY INTO PARTICLES OF DESRED SIZE AND SHAPE, H. DRYING SAID PARTICLES, AND I. CALCINING IN THE PRESENCE OF AN OXIDIZING ATMOSPHERE THE DRIED PARTICLES TO INCORPORATE OXYGEN ATOMS, INTO THE MATRIX AND TO ACHIEVE THE REQUISITE CO-PRECIPITATED UNIFORMLY DISPERSED ACTIVE AND CARRIER MATERIAL, HARDNESS AN SURFACE AREA.
