Embodiment 1
[0053] 1. To prepare amorphous nano-spherical active iron phosphate hydrate, the following steps are adopted:
[0054] (1) Weigh 2 grams of urea, dissolve it in 50ml of distilled water, and stir for 30 minutes to obtain solution 1;
[0055] (2) Weigh 1 gram of sodium dodecyl sulfate (SDS), dissolve it in 50ml of distilled water, and stir for 30 minutes to obtain solution 2;
[0056] (3) Mix solution 1 and solution 2 to obtain solution A;
[0057] (4) Weigh 1.01 g (2.5 mmol) of ferric nitrate nonahydrate as an iron source, dissolve it in 90 ml of distilled water, and stir for 30 minutes to obtain ferric nitrate nonahydrate solution;
[0058] (5) Add the ferric nitrate nonahydrate solution obtained in step (4) dropwise to solution A obtained in step (3), and stir for 30 minutes to obtain solution B;
[0059] (6) Weigh a phosphoric acid solution with a mass concentration of 85%, the molar ratio of phosphoric acid in the phosphoric acid solution to the ferric nitrate nonahydrate...
