| dc.description.abstract | This study aims to determine the ability of desorption and the interaction between the
white sand contaminated with metal ions (Cd2+) 50 ppm with various concentrations
of SDS and the SDS Flow Rate Variations on SDS solution at pH 7. The
concentration of SDS used is 0; 0.5; 1; 2; and 5 cmc. Variations in flow velocity SDS
used is 2, 4, 6, 8, and 10 ml / min. This study is divided into two steps: pretreatment
by sand contamination that begins with washing and drying until the conditions are
uniform. Then proceed with the measurement of the adsorption capacity potential by
batch adsorption system. Second Stage performed remediation phase or washing with
SDS to review the desorption capabilities and interaction between SDS and white
sand is contaminated (Cd2+). Effect of SDS concentration in removing metal ions or
washing the metal ion (Cd2+) looks volatile, caused by the channeling effect that can
not be controlled. The removal results contained in the current The concentration
SDS 2 SDS cmc with a flow rate of 4 ml / min, 11.27%. Effect of flow rate variation
was significant only at the time of 0 cmc or no addition of SDS, suggesting
remediation process is influenced by the SDS The concentration if their Channeling
Effect that can not be controlled. Sampling every four pore volume or desorption
kinetics shows constant returns after 12 pore volumes of up to 16 pore volumes, this
indicates that the dominant channeling effect on 12 pore volumes of up to 24 pore
volumes. | en_US |
