Penentuan Kadar Amoniak Pada Air Reservoir di PDAM Tirtanadi Instalasi Pengolahan Air Limau Manis Secara Spektrofotometri

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.
