Abstract: The analysis of lead
(Pb) and iron (Fe) analysis have been done in Taipa’s sea water. The objective
is to determine the level of lead and iron metals using spectrophtometry
method. The sea water samples were taken in the morning and afternoon at three
different places. The distance of 3 samples are approximately 5 m, 10 m, and 15
m from the harbour and about 5 m from the seashore. The result of the analysis
level of lead and iron metals from 3 points for lead taken in the morning,
point A is 0.919 mg/L, point B is 0.703 mg/L, and point C is 0.810 mg/L. While,
taken in the afternoon, the lead level point A is 0.729 mg/L, point B is 0.837
mg/L, and point C is 0.729 mg/L. For the iron level taken in the morning, point
A is 0.394 mg/L, point B is 0.546 mg/L, and point C is 0,324 mg/L. Meanwhile,
in the afternoon the iron level, point A is 0.449 mg/L, point B is 0.365 mg/L,
and point C is 0.504 mg/L. The concentration of lead metal in the sea water is
in range 0.703 mg/L – 0.919 mg/L. The concentration is higher than limit ranges
value of lead metal 0.025 mg/L. The concentration of iron metal in the sea
water of Taipa’s harbor is about 0.324 mg/L – 0.546 mg/L. It’s concentration is
higher than limit for value iron metal 0.01 mg/L.
