Abstract
The invention relates to a process of preparing a composition for natural and waste waters purification, by heating and stirring and acid titanium-containing solution with metal compounds selected from the group consisting of Group I-Group V and Group VIII of the periodic table of elements by heat treating said compounds with titanium solutions in at least two heating steps and introducing additional compounds (trivalent titanium compounds and metal oxides).
Claims4
A process of preparing a composition, for natural and waste waters purification, by heating and stirring an acid titanium-containing solution with compounds of metals selected from the group consisting of Groups I,IV and V of the Periodic Table, wherein the heating is carried out in at least two steps:
- in the first step it is carried out at the minimum rate of at least 3° C./min at a temperature in the range of 10-90° C., and in the second step the rate is slowed down to 1° C./min and is carried out for 0.5-2 hours at a temperature in the range of 95° C.-105° C., and then the third step is carried out for 0.5-2 hours at a temperature in the range of 105° C.-120° C.
A process of preparing a composition, for natural and waste waters purification, by treating metals compounds selected from the group consisting of Groups I-V and VIII of the Periodic Table with an acid titanium-containing solution with continuous stirring and heating, wherein the treatment is carried out by heating in at least two steps:
- wherein the first step is carried out at the minimum rate of at least 3° C./min at a temperature in the range of 10-90° C., then the rate is slowed down to 1° C./min and the second step is carried out for 0.5-2 hours at a temperature in the range of 95° C.-105° C., and then the third step is carried out for 0.5-2 hours at a temperature in the range of 105° C.-120° C. with a one time injection of trivalent titanium compound.
