, 2018 硫酸烧渣作为重要的二次资源,除砷有利于提高烧渣的价值.针对某含砷硫酸烧渣预处理脱砷的问题,采用Na_2S-Na OH体系浸出烧渣中的砷.首先采用单因素试验确定Na_2S和Na OH的药剂用量范围,进而采用响应曲面法优化浸出工艺参数.结果显示,响应曲面法优化Na_2S-Na OH体系中浸出砷的模型显著,Na_2S、Na OH和温度均对砷的浸出有着重要影响,且温度越高越有利于砷的浸出,Na_2S和Na OH之间存在明显的交互作用,在80℃、Na OH浓度为0.34 mol·L~(-1 ...

, 2012 对湖南省水口山矿冶周边土壤进行采样分析,以土壤砷总量与有效态砷含量以及土壤基本理化性质(pH、有机质含量、土壤粘粒含量)为参数,研究各参数在两种土地利用类型(菜地土和水稻土)间的差异以及有效态砷与土壤理化性质之间的关系。结果表明,水口山水稻土与菜地土平均砷含量分别达72.01和30.71mg.kg-1,接近或已超过国家土壤环境质量二级标准;两种土地利用类型的土壤基本理化性质差异显著,水稻土粘粒含量、有机质含量显著高于菜地土,pH则显著低于菜地土,水稻土存在明显的酸化现象 ...
