abstract
Contamination of iron was examined for different types of polyethylene bottles (Nalgene bottles and Sanplatec Clean bottles) and their washing treatments (Milli-Q and 10% nitric acid). Milli-Q water which was contained in these bottles and frozen at -20℃ for 13 days was analyzed by chemiluminescence method. The contamination level of Fe (II) was the most lowest in Nalgen bottles washed with 10% nitric acid and Milli-Q water. On the other hand, for Sanplatec Clean bottles, the contamination level of Fe (II) was lower in no treatments (just unpacked for use) than those washed with nitric acid.
