ANALYSIS OF LEAD (PB) IN REFILL DRINKING WATER AT SUMBERSARI VILLAGE, MALANG CITY

Abstract

Drinking water is water whose quality meets health requirements and can be drunk directly, the health requirements in question are microbiology, chemistry, physics, and radioactivity. Therefore, before drinking water is consumed, it must meet these requirements to be safe in the body. One of the requirements in drinking water is chemical requirements in the form of lead metal (Pb). Lead (Pb)is a heavy metal that is a neurotoxin that can enter and accumulate in the human body so that the harmful effects on the body are increasing. This study aims to determine the levels of Pb in refill drinking water at the Refill Drinking Water Depot, Sumbersari Village, Malang City according to the Regulation of the Minister of Health Number 492 of 2010. The research method used is atomic absorption spectrophotometry. The procedure carried out was sample preparation in the form of refill drinking water using the wet digestion method using HNO3 and making 100 ppm Pb mains, 1.5, 10, 15, and 20 ppm working solutions. The determination of Pb levels was carried out using an atomic absorption spectrophotometer with a wavelength of 283.3 nm. The results showed that the levels of Pb in the three samples were 0.0000 ppm, which means that the refill drinking water sample did not contain Pb.
