Kajian Pengaruh Kehadiran Kontaminan Organik Dan Nonorganik Terhadap Produksi Busa SDS Pada Foam Generator

Abstract

This study aims to determine the capacity and stability of Sodium Dodecyl Sulfate foam (SDS) continuously and dynamically to variable changes in surfactant concentration of SDS in the presence of Cd2+ metal contaminants and Black Coffee on foam generator. The SDS consentations used are 1x cmc, 2x cmc and 3x cmc. The concentration variations of Cd2+ and Black Coffee used are 10, 20, 30, 40 and 50 ppm. The foam capacity measurement is done by contacting the SDS solution and the contaminant with the N2 gas in the foam generator, on the foam stabiitas measurements made when the foam on the foam generator has been constant and then the foam is fed into the measuring cup for foam stability. Result of analysis of effect of SDS concentration to foam capacity for 10 minutes for contaminant Cd2+ and 11 minutes for coffee contaminant. Obtained by foam height 1x cmc, 2x cmc, and 3x cmc with influence of Cd2+ with concentration 50 ppm equal to 8,3; 8.4 and 8.8 cm while for coffee contaminants with a concentration of 10 ppm of 4; 4.2 and 4.3 cm. Foam stability analysis results obtained stable foam (foam height in measuring glass does not change anymore) at 25 minutes.
