Embodiment 1
[0036] Prepare a mixed solution of 10.5g ammonium chloride, 10.6g phosphotungstic acid (containing 44 crystal waters) and 100mL water, then immerse 40g of 13X molecular sieve particles into the prepared mixed solution, and stir at 60°C for 9 hours. Dry at 120° C. to obtain carrier particles loaded with active components. The carrier particles loaded with active components are immersed in a mixed solution prepared by 68%-70% nitric acid (50-100ml) and 50% hydrogen peroxide (50-100ml) until no more gas is generated. After the particles were filtered out, they were washed with distilled water and the pH value was determined to be 3. Under the condition of calcination temperature of 250° C., calcine for 10 hours to obtain the finished cleaning agent. Active components of the purifying agent: 5.0% by mass of ammonium chloride, 4.0% by mass of phosphotungstic acid, and 91.0% by mass of the carrier.
Embodiment 2
[0038] Weigh 14.6g of ammonium chloride, 13.3g of phosphotungstic acid (containing 44 crystal waters) and 100mL of water to prepare a mixed solution, then immerse 40g of 13X molecular sieve particles into the prepared mixed solution, and stir at 50°C for 10 hours. Dry at 90°C to obtain carrier particles loaded with active components. The carrier particles loaded with active components are immersed in a mixed solution prepared by 68%-70% nitric acid (50-100ml) and 50% hydrogen peroxide (50-100ml) until no more gas is generated. After the particles were filtered out, they were washed with distilled water and the pH value was determined to be 4. Under the condition of calcination temperature of 200° C., calcination is carried out for 12 hours to obtain the finished cleaning agent. Active components of the purifier: 7.0% by mass of ammonium chloride, 5.0% by mass of phosphotungstic acid, and 88.0% by mass of the carrier.
Embodiment 3
[0040] Prepare 8.3g of ammonium chloride, 11.2g of phosphotungstic acid (containing 44 crystal waters) and 100mL of water to make a mixed solution, then immerse 40g of 13X molecular sieve particles into the prepared mixed solution, and stir at 80°C for 8 hours. Dry at 150° C. to obtain carrier particles loaded with active components. The carrier particles loaded with active components are immersed in a mixed solution prepared by 68%-70% nitric acid (50-100ml) and 50% hydrogen peroxide (50-100ml) until no more gas is generated. After the particles were filtered out, they were washed with distilled water and the pH value was determined to be 3. Under the condition of calcination temperature of 300° C., calcination is carried out for 8 hours to obtain the finished cleaning agent. Active components of the purifier: 4.0% by mass of ammonium chloride, 3.0% by mass of phosphotungstic acid, and 93.0% by mass of the carrier.
