Sodium lignosulfonate as sacrificial agent and effectiveness in reducing CTAB cationic adsorption onto kaolinite
Sodium lignosulfonate (SLS) as sacrificial agent (SA) was investigated on the effectiveness in reducing Cetyl Trimethyl Ammonium (CTAB) cationic surfactant adsorption. X-Ray diffractometer (XRD), X-Ray fluorescent (XRF), Scanning electron microscopy (SEM), electron dispersive X-Ray (EDX) and Brunaue...
