Shuitu Baochi Xuebao, 2002 用室内模拟淋洗土柱的方法 ,对棕壤和褐土的酸淋容特征进行了研究。结果表明 ,p H低的酸雨使棕壤严重酸化且有活性铝测出 ,但对褐土的影响相对较轻。 4种盐基离子淋失总量与酸雨的氢离子浓度呈极显著的正相关关系 ,淋失量 Ca2 >Mg2 >Na >K ,其中 Na 对酸雨的酸度最不敏感。电导率的变化与盐基淋失量的变化有相同趋势 ,但不同处理之间的差别倍数大于盐基淋失差别的倍数 ,4种酸雨对土壤的危害程度为 p H2 >p H3>p H4、p H5 ,其中危害棕壤的程度高于褐土。

Gongye shui chuli隧道施工废水具有高悬浮物、高矿化度和高碱性特征，其固液分离效率受颗粒聚集行为显著影响。以典型炭质板岩颗粒为研究对象，系统考察了不同阳离子（Na⁺、K⁺、Ca2+、Mg2+）类型与浓度对颗粒聚集动力学的影响机制。结果表明，炭质板岩颗粒表面富含羟基官能团，可通过氢键或配体交换作用促进自聚集。离子价态与浓度对聚集效率具有主导调控作用，二价离子（Ca2+、Mg2+）因更强的电荷屏蔽与双电层压缩效应，使颗粒临界聚集浓度（CCC）较一价离子低1~2个数量级，符合Schulze–Hardy规律 ...
