The fixed bed column sorption study for the nitrate removal by a cationic modified inedible pumpkin shell

Th(IV)/U(VI) Sorption on Modified SBA–15 Mesoporous Materials in Fixed–Bed Column

The sorption of thorium and uranium ions by functionalized SBA–15 mesoporous silica materials with Schiff base ligating groups N–propylsalicylaldimine (SBA/SA) and ethylenediaminepropylesalicylaldimine (SBA/EnSA) from aqueous solution was investigated in fixed-bed column method. The TEMPeffect of pH, sample solution volume, and the column design parameters such as sample and eluent flow rat...

Disinfection and removal performance for Escherichia coli and heavy metals by silver-modified zeolite in a fixed bed column

Fixed Bed Column Study on the Removal of Chromium (iii) Ions from Aqueous Solutions by Using Hemp Fibers with Improved Sorption Performance

Cr (III) removal from aqueous solutions by sorption in a fixed bed column filled with alizarin S impregnated hemp fibers has been studied. The effect of the initial metal ion concentration on the Cr (III) sorption process was investigated and the experimental breakthrough curves were obtained. The breakthrough time and saturation time decreased from 110 min to 80 min and from 300 min to 160 min...
