Monovalent acidic pesticide sorption can be determined for any soil pH if the dissociation constant of the compound is known, and sorption coefficients are available for at least two different pH values, measured in a wide enough range to enable estimating both neutral and anionic form coefficients. Sorption estimates have also been made from a single sorption coefficient available, assuming a non‐compound specific value of the anionic form sorption coefficient or considering a generic ratio between sorption coefficients of the two forms. A compound‐specific procedure for adjustment of parameters of the equation for estimating sorption of monovalent acidic herbicides at different pH levels, from a single sorption coefficient, is proposed and evaluated.

使用单个吸附系数估算在不同pH值下一价酸性除草剂的吸附量。

如果已知化合物的解离常数，则可以确定任何土壤pH值对一价酸性农药的吸附，并且在至少两个不同的pH值上都可获得吸附系数，该吸附系数的测量范围足够广，可以估算中性和阴离子形态系数。假设阴离子形式的吸附系数的非化合物特定值或考虑两种形式的吸附系数之间的一般比率，也可以从一个可用的吸附系数进行吸附估算。提出并评估了一种用于调整方程式参数的化合物特定程序，该方程用于从单个吸附系数估算不同pH水平下一价酸性除草剂的吸附。
