稻壳炭添加比例对红壤镉形态转化的动态影响
Dynamic Effects of Rice Husk Charcoal Addition Ratio on Cadmium Speciation Transformation in Red Soil
摘要
Abstract
This study investigated the effects of different application rates of rice husk charcoal on Cd speciation distribution and soil pH in Cd-contaminated soil through laboratory cultivation experi-ments.Results indicated that rice husk charcoal significantly increased soil pH,with all treatment groups maintaining higher pH levels than the control group.Concurrently,exchangeable Cd content decreased across all treatment groups.Carbonate-bound Cd continuously increased throughout the in-cubation period in the rice husk charcoal treatment group.Iron-manganese oxide-bound Cd and resi-due-bound Cd also showed a gradual increase trend in the treatment groups.Overall,adding 3％rice husk charcoal yielded the best Cd immobilization and remediation effect in red soil under the experi-mental conditions of this study.关键词
