Soil contamination is a predominant issue today in China. Recently, different remedies have been implemented to effectively immobilize contaminants, such as heavy metals, from soil. This project studied the efficiencies of phosphate in fish bones and aluminosilicate in clay to immobilize cadmium, chromium, copper, lead, and zinc in a heavily contaminated sample of yellow-brown soil from the Hetao region of Inner Mongolia, China. The heavy metals found in samples of soil were sequentially extracted and analyzed by atomic absorption spectroscopy. Results showed that both samples had the most significant immobilization fraction during the first two weeks of treatment, and that agent A was best to treat chromium and zinc, while agent B was favorable to treat cadmium, copper, and lead.
