Examples
Example Embodiment
[0042]Example 1
[0043]Add 0.5g of SiO to 100mL of drinking water (with a cadmium ion concentration of 0.2ppm)2@Rosin-based macroporous adsorption resin, pH=6.0, shaking at a constant temperature of 30°C for 70min. The removal rate of cadmium ions can reach 96.94%.
Example Embodiment
[0044]Example 2
[0045]Add 0.6g of SiO to 100mL of drinking water (with a cadmium ion concentration of 0.2ppm)2@Rosin-based macroporous adsorption resin, pH=6.0, shaking at a constant temperature of 30°C for 70min. The removal rate of cadmium ions can reach 98.66%.
Example Embodiment
[0046]Example 3
[0047]Add 0.8g of SiO to 100mL of drinking water (with a cadmium ion concentration of 0.2ppm)2@Rosin-based macroporous adsorption resin, pH=6.0, shaking at a constant temperature of 30°C for 70min. The removal rate of cadmium ions can reach 98.66%.
