腐殖质对膨润土分散体聚集的影响

<jats:p>The structure of the soil is significantly affected by the presence of humic substances. The purpose of our study was to study the effect of humic acid on the hydrophilicity of clay particles and on the stability of clay dispersions. Stability of dispersion was evaluated by the turbidimetric method. The hydrophilicity of the clay was estimated by the contact angle method. Extreme dependence of the contact angle on humic acid concentration was observed, which was confirmed by turbidity data.</jats:p> <jats:p>土壤结构受腐殖质的显著影响。本研究旨在探讨腐殖酸对黏土颗粒亲水性和黏土分散体稳定性的影响。采用浊度法评价分散体的稳定性 并采用接触角法测定黏土的亲水性。结果表明 接触角与腐殖酸浓度呈极强的相关性 浊度数据也证实了这一点</jats:p>
