PENENTUAN KADAR AMONIAK PADA AIR RESERVOIR DI PDAM TIRTANADI IPA LIMAU MANIS SECARA
SPEKTROFOTOMETRI
ABSTRAK
Telah dilakukan penentukan kadar amoniak pada air reservoir di PDAM Tirtanadi IPA Limau Manis dengan menggunakan metode spektrofotometri. Sampel ditambahkan mineral stabilizer, polivinyl alcohol dispersing agent dan reagent nessler dan diukur kadar amoniaknya dengan menggunakan spektrofotometer DR 2800 pada panjang gelombang 380 nm. Dari hasil pemeriksaan diperoleh kadar amoniak rata - rata adalah 0,03 mg/l. Kadar amoniak ini masih memenuhi persyaratan kualitas air minum menurut Keputusan Menteri Kesehatan No.492/Menkes/Per/IV/2010 tanggal 19 April 2010 yaitu 1,5 mg/l.
DETERMINATION OF AMMONIA IN THE WATER RESERVOIR IN PDAM TIRTANADI IPA LIMAU MANIS
BY SPECTROPHOTOMETRY
ABSTRACT
Determination of ammonia in the water reservoir in PDAM Tirtanadi IPA Limau Manis by spectrophotometry have done. Sample was added mineral stabilizer, polyvinyl alcohol dispersing agent and nessler reagent and quantified content of ammonia using DR 2800 spectrophotometer at wavelength of 380 nm. From the results obtained average ammonia contents is 0,03 mg / l. The ammonia contents still meet water quality requirements according to the Decision of the Minister of Health No.492/Menkes/Per/IV/2010 date April 19, 2010 is 1,5 mg / l.
