Evidence Details

Equipment evidence

The slurry was put into a microwave-ultrasonic combined synthesis extractor (XH-300A, Beijing Xianghu Technology Co., Ltd., China) for reaction synthesis (microwave power 600 W, ultrasonic power 200 W, reaction temperature maintained at 80 ◦C, working for 2 s and stopping for 1 s, reaction time 15 min).

Source evidence

Using DTPA/sodium bicarbonate extractant to extract bioavailable Pb, Cd and As in soil after Fe-HAP remediation for 60 days, the immobilization efficiencies were 79.77%, 51.3% and 37.5% for Pb, Cd and As, respectively.

Source evidence

The estimated maximum adsorption capacities of Cd2+, Pb2+ and As(V) on Fe-HAP were 476.2 mg g−1, 1322.5 mg g−1, and 195.69 mg g−1, respectively.
