Abstract

Research of indigo carmine dye adsorption using natural zeolite modified by cetyltrimethylammonium bromide (CTAB) surfactant has been done. The purpose of this study was to modify the natural zeolite using CTAB surfactant and to determine its ability on the adsorption of indigo carmine dye. The stages of the study included the activation of zeolites, modifying zeolites using CTAB surfactant and adsorption test of indigo carmine dye. The results showed that the zeolites could be modified by CTAB. They were then characterized by the existence of FTIR absorption band at wavelengths of 1404.18 cm-1 and 2800-3000 cm-1. The various concentration of indigo carmine (5, 10, 15, 20 ppm); contact time (15, 30, 45 minutes) and pH (3, 4, 5, 6, 7, 8, 9) were studied and the highest condition was reached at the 45 minutes, pH= 3 and indigo carmine concentration of 20 ppm for 0.5 and 1 mM CTAB (15.35% and 23%) and indigo carmine concentration of 5 ppm for 10 mM CTAB (96.18%). The adsorption of indigo carmine tended to increase with increasing the concentration and contact time and decreased with increasing the pH.

Abstract

Study on the physical characteristics, chemical content of water as well as microbiological composition in the area of ​​geothermal hot springs in Gedongsongo have been done. Water samples were collected on the area within streaming water with moderate temperature. The selection was done on the basis of water that will enter into agricultural and residential areas. Water analysis includes physical analysis, such as temperature, water clarity and odor. While the chemical analysis comprised the oxide content of Mg and Ca. Anion analysis was also performed as sulfate, phosphate, bicarbonate and chloride. The microbiological composition performed using SSCP method for community analysis. The results showed a correlation between the temperature and the content of the anions. The higher temperature of water showed the higher level of anions. The existence of the metal oxide is directly proportional to the levels of the anions. The lower acidity of water showed the higher the levels of hydrogen sulfide. Bacterial composition based on SSCP profile showed a slight different of diversity.
