摘要
用平衡吸附法研究了柠檬酸、草酸对土壤氟吸附的影响,并提出有机酸影响氟吸附的可能机理。实验结果表明:有机酸对土壤氟吸附有较大的影响:(1)当有机酸处于低浓度时,土壤氟吸附量随浓度升高而增加;高浓度时,土壤氟吸附量随浓度升高而降低;(2)在有机酸存在条件下,土壤氟的吸附量与平衡氟浓度间呈极显著的直线正相关或负相关。
The paper presents the possible mechanism of effect of organic acid on F1 absorption with equilibrium absorption methods. Experiments show that organic acid has a great effect on soil F1 absorption. When the organic acid concentration is low, the amount of F1 absorption increases. While the organic acid concentration is high, the result is the opposite. Under the condition of organic acid, the amount of F1 absorption and equilibrium F1 concentration are clearly shown as linear positive or negative relationship.
