Fig. 3. Spin–spin relaxation time (T₂) values for d₆–benzene and -C₆D₅ of d₈–toluene in suspensions of the untreated soil fraction and the soil fraction treated with NaOH as a function of pH (1:200 soil to solution ratio, 0.01 M NaCl). ${diamond}$ d₆–benzene for untreated soil; ${square}$ -C₆D₅ of d₈–toluene for untreated soil; ${diamondsuit}$ d₆–benzene for treated soil; ${blacksquare}$ -C₆D₅ of d₈–toluene for treated soil.
