Abstract

The quantitative analysis of nitrate and nitrite in rain, milk and infant formula was done by Ion Chromatography. The nitrite was not detected(<0.1 mg/L) in all the samples. However, the nitrate was detected in the range of 0.1~4.9 mg/L in rain, 9.8~19.8 mg/L in milk, and 80~300 mg/L in infant formula, respectively. Some content of nitrate is close to the maximum contaminant level(MCL) which is 10 mg/L as <TEX>$NO_3-N$</TEX>, 44.3 mg/L as <TEX>$NO_3$</TEX>.
