Penentuan Kadar Amoniak pada Air Reservoir Sunggal di Pdam Tirtanadi Secara Spektrofotometri

Abstract

Ammonia content contained in the water is one parameter that must be analyzed interms of determining the qualitty of drinking water.Ammonia is a gas which has an unpleasant odor, large amounts of ammonia can be poison Ammonia in water is usually found as ammonium.To determine levels of ammonia in water sampels can be performed using spectrophotometric methhod. Where the first sampel on was added stabilizer and dispersing agent poliphinyl alcohol and nessler reagen. Using a spectrophotometer at a wavelength of 425 nm, the ammonia can be determined. From the results of levels of ammonia in the water reservoir at the taps obtained Tirtanadi averange levels of ammonia in the water reservoir revolve 0,012mg/l util 0,051 mg/l. Ammonia levels are stiil meet water quality requirements according to the Ministry Of Health Decree No.492/MENKES /Per/SK/Iv/2010 date 19 1 April 2010 is 1,5mg/l. This suggests that the levels of ammonia in water reservoir is still far below the established water quality standard of processed taps become Tirtanadi still good and suitable for consumption by the public.
