Popis: The collected soil samples of Jining area were subjected to microwave digestion (HNO3 + HF + H2O2), and the absorbance of the organic phase MIBK was determined by flame atomic absorption spectrophotometry after extraction with KI-MIBK. Results According to the measured results, within 20 meters, the content of cadmium increased gradually with increasing distance, and gradually decreased with increasing distance after 20 meters. The content of cadmium in the soil shows a clear change trend due to the distance from the source of pollution. Based on this change, favorable conditions suitable for crop growth can be created.
