preparation example 1
[0029] Preparation Example 1 The preparation method of modified magnetic jade powder is as follows:
[0030] S1. Pretreatment: further grind 10g jade powder and 2.5g ferric oxide powder respectively, pass through a 200-mesh sieve, soak 200mL in 7wt% NaOH or KOH solution for 1h, filter, wash, dry, and the drying temperature is 95°C, drying time is 3h, mix well to get magnetic jade powder;
[0031] S2. Grafting of borneol: Add 10g of magnetic jade powder to 100mL of 7wt% ethanol solution of silane coupling agent KH560, heat to 70°C for 2 hours, filter, wash, add to 100mL of toluene, dissolve and mix with 1g of borneol , add 0.5g triethylamine dropwise, heat to 95°C, react for 3h, filter, wash the solid with toluene, dry to obtain borneol-grafted magnetic jade powder;
[0032] S3. Modification: add 10g of the obtained borneol-grafted magnetic jade powder into 100mL 3.5wt% ethanol solution containing silane coupling agent, heat to 85°C, react for 2h, filter and wash to obtain mod...
