Enhanced Removal of Bordeaux B and Red G Dyes Used in Alpaca Wool Dying from Water Using Iron-Modified Activated Carbon

The aim of this research was to explore the removal Red G and Bordeaux B dyes from water using a packed bed column with conventional carbon (C-conv) iron-modified activated (C-FeCl3). bands increased in C-FeCl3, corresponding groups already existing C-conv, such as C = C-C, appearance new groups, C-O, C-Cl, Fe-Cl Fe-O. total ash content (CT) CT (10.53 ± 0.12 8.98 0.21)% for C-conv respectively. A molecular structure shape cross noticed B, which less complex smaller than one G. For fixed-bed columns, fraction (0.43 0.85) mm. pH adsorbents 8.55 4.14 C-FeCl3. Breakthrough curves were obtained Thomas model (TM) Yoon–Nelson (YNM) applied. sorption capacity on C-FeCl3 qTH: (237.88 216.21) mg/g, respectively, but (338.46 329.42) mg/g. dye (RT) over 55%.
