Penentuan Kadar Klorida pada Air Sumur dan Air Limbah dengan Spektrofotometer Portable Dr/2010

Abstract

The liquid waste is wastewater from households, industry, and the other place. If wastewater too much thrown into the land, river, lake, and the sea, it can make negative effect to quality of environment. One of chemical contains in the water and wastewater is chloride. Chloride is one of the ingredients that are very dangerous to survival if it exceeds a defined threshold. It is necessary for determination of chloride in water and wastewater. Determination of chloride content in well water and wastewater with a spectrophotometer portable DR/2010 of the reacting water and wastewater samples with mercuric thiocyanate solution and ferric ion solution that produce complex penta-aquot-thiocyanate iron (III) chloride is then measured levels of chloride in the wavelength of 455 nm. Chloride levels are obtained for a sample of well water at 6,0 mg/l, 5,4 mg/l, 3,83 mg/l, 5,0 mg/l, and 7,5 mg/l, while for wastewater samples by 23,4 mg/l, 24,2 mg/l, 232 mg/l, 467,6 mg/l, and 62,5 mg/l. The results obtained from the chloride levels in the well water and wastewater in accordance with the defined quality standards.
