From: Thermodynamic, kinetic, and isotherm studies of Direct Blue 86 dye absorption by cellulose hydrogel
DB86 dye absorption on CAH as a pH impact (a) on the removal %; (b) on the absorption capacity [DB86 dye (50 ppm), adsorbent (1.5 g/L), time of contact (3 h), shacking (200 rpm), and temp. (27 ± 2 °C)].
