  • The best modification conditions were as follows: mass ratio (m x /m 1 %) Na 2 CO 3 20.00%, NaHSO 3 10.00% and Na 2 SO 3 0.10%, the reaction temperature is 105°C reflux reaction time 3 h. The surface wettability of the walnut shell filter material before and after modification reversed from lipophilic to hydrophilic.
