多级沉淀法处理含砷废水

, 2017
提出了一种处理低浓度含砷废水的新方法,通过控制pH值进行多级沉淀得到了含水率低、过滤性能良好、性质稳定的固砷沉淀.使用该法处理1 g/L的低砷废水,在Fe/As摩尔比为7.9、初始pH 1.5、反应温度95℃、终点pH 6.0的条件下的除砷率可达100%.

陕南土壤中水溶态硒、氟的含量及其在生态环境的表征

, 2005
以陕南早古生代地层上发育的土壤为材料,研究土壤中水溶态硒、氟的含量及其与总量、土壤pH值之间的关系,探讨土壤水溶态硒、氟含量在生态环境中的表征作用.结果表明,陕南土壤中水溶态硒、氟的平均含量分别为0.012μg·g-1和0.87μg·g-1,土壤中水溶态硒、氟的含量同其总量之间都存在着显著的正相关关系;在供试土壤pH范围内(5.10—7.52),水溶态硒的含量随pH值的增加先降后升,水溶态氟随pH值的增减而同步增减,其相互间的关系均可用函数方程式定量表达.水溶态硒含量能较好地表征陕南的高硒生态环境 ...
