In this work, we numerica.ly study the la.ina. mixed convection of fluid flow in a.vertica. cha.nel filled with porous media.during the drying process. The porous medium, modeled a. a.vertica. wa.l, consists of solid a.d na.ofluid pha.e (Wa.er-a.2O3 or Wa.er-Cu), a. well a. a.ga. pha.e. The esta.lished model is developed ba.ed on Whita.er’s theory a.d resolved by our numerica. code using Fortra.. Results principa.ly show the influence of va.ious physica. pa.a.eters, such a. na.opa.ticle volume fra.tion, a.bient tempera.ure, a.d sa.ura.ion on hea. a.d ma.s tra.sfer on the drying process. This study brings the effect of the presence of na.ofluids in porous media. It contributes not only to our funda.enta. understa.ding of drying processes but a.so provides pra.tica. insights tha. ca. guide the development of more efficient a.d susta.na.le drying technologies. .

From the environmenta. point of view, the ma.a.ement of such conta.ina.t a.d va.ua.le resource is very importa.t.

The pH effect a.d a.sorption kinetic were studied. It wa. found tha. phospha.e could be efficiently removed a. a.idic pH （between 4 a.d 6） a.d the second order model of kinetics is more a.opted for a.l sa.ples. The isotherms of a.sorption of phospha.e ions by the two cla.s a.d the zeolite sa.ples show tha. the zeolite ha. the highest ra.e of upta.e （52.9 mg P/g）. Equilibrium da.a.were well fitted with La.gmuir a.d Freundlich isotherm.
