[0024] Example 1: Ultrasonic repair method of heavy metal compound contaminated soil
[0025] The contaminated soil was collected from Cd, Cu, Pb and Zn compound contaminated soil near a copper smelter in Fuyang City, Zhejiang Province. After removing stones and residual roots, the air-dried soil samples were ground through a 2 mm stainless steel sieve, and part of the soil samples were further ground through a 0.15 mm nylon sieve. The contents of cadmium, copper, lead and zinc in the soil were determined to be 13.3 mg·kg -1 , 740 mg·kg -1 , 426 mg·kg -1 And 2133 mg·kg -1 . After pretreatment, weigh 1.0000 g of soil sample and add it to a 100 mL centrifuge tube.
[0026] The subsequent steps of shaking extraction are as follows:
[0027] (1) The concentration of the citric acid solution is 1.0 mol·L -1 ;
[0028] (2) Mix according to the solid-liquid ratio of 1:25, the above soil sample is 1.0000 g, and the volume of the citric acid solution is 25
[0029] mL;
[0030] (3) Mechanical ...
