Experimental Studies on the Stabilization of Heavy Metal Soils Heavily Polluted by Lead and Zinc Smelting
Some lead and zinc smelting sites suffer from severe heavy metal pollution.In response,FeCl3+CaCl2+NaOH+Ca(OH)2,FeCl3+CaCl2+NaOH+Ca(OH)2+Na2S and FeCl3+Na2HPO4,iron-based stabilisation materials were used for remediation.The effectiveness was assessed by the TCLP leaching method,and FeCl3+Na2HPO4 was particularly recommended as the combination resulted in a 96%,63%,and 61%reduction in Pd leaching concentration in the three sites,respectively,significantly reducing heavy metal migration.This study highlights the importance of suitable material selection for effective soil stabilisation.
