Studi tentang Kesensitifan Spektrofotometer Serapan Atom (SSA) Teknik Vapour Hydride Generation Accessories (VGHA) dibandingkan dengan SSA Nyala pada Analisa Unsur Arsen (As) yang terdapat dalam Air Minum

Abstract

Vapour hydride generation accessories (VHGA) is equipment that is combine to atomic absorption spectroscopy(AAS) in analysis metal so that the instrument can achieve sensitivity to μg/L (ppb). The Investigation of AAS technics VHGA versus flame AAS on analysis As and assayed As on water sample of P DAM Tirtanadi has been conducted. Sampling point on storage water treatment plant (WTP) Sunggal storage and deep well booster Simalingkar storage that is monitored for three month from March until may 2009. The yield of absorbance using AAS technic VHGA view increment up to 10.429,8 fold As contents on WTP Sunggal storage was 8,8018 ppb; 9,3429 ppb; 9,0337 ppb alternately and the contents on deep well booster Simalingkar storage was 8,8459 ppb; 8,9895 ppb; 8,5699 ppb alternately The result of analysis absorption using SSA technics VHGA appropriate to As. As contents on water of WTP Sunggal storage and deep well booster Simalingkar storage accomplishing requirement in favor KEP MENKES RI No 907 I MENKES I VII I 2002.
