For this purpose, sequential extraction tests were performed on the fly ash treated with magnesium chloride. In addition, pH-dependent tests were conducted on fly ash treated with magnesium chloride or existing insolubilizers. The leaching concentration of lead was decreased with the addition of magnesium. The leaching concentration of lead from fly ash treated with a magnesium addition rate of 1.0 mol/kg or more could meet the Japanese landfill standard of lead. The pH of leachate was decreased with the addition of magnesium. The reason for this decrease of pH could be that hydroxide ion was consumed by the reaction of magnesium ion with hydroxide ion to form magnesium hydroxide precipitate. Chlorine in magnesium chloride did not affect the insolubilization of lead in fly ash by the addition of magnesium chloride. The suppressive effect of magnesium treatment on lead leaching in case of decrease in pH was similar to that of chelate treatment, but inferior to that of cement treatment. It would be said that the mechanism of insolubilization of lead in fly ash treated with magnesium chloride was carbonation of lead in the curing and drying steps, in addition to the decrease of lead solubility due to decrease in pH by the addition of magnesium.","subitem_description_language":"en","subitem_description_type":"Abstract"}]},"item_10002_identifier_registration":{"attribute_name":"identifier_registration","attribute_value_mlt":[{"subitem_identifier_reg_text":"10.34481/0002000809","subitem_identifier_reg_type":"JaLC"}]},"item_10002_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"宮崎大学工学部","subitem_publisher_language":"ja"},{"subitem_publisher":"Faculty
