| dc.description.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. | en_US |
