NITRATE ION SELECTIVE ELECTRODE

摘要

PROBLEM TO BE SOLVED: To provide a nitrate ion selective electrode capable of eliminating the need for complicated pretreatments, being extremely easily operated for measurements such as the immersion of the electrode in a sample liquid such as non-industrial waste water, and highly accurately measuring the concentration of nitrate ions without being affected by chloride ions.;SOLUTION: The nitrate ion selective electrode 1 is provided with a nitrate ion responsive film 3 at a tip part 2A of a body 2 and an internal liquid 5 and an internal electrode 6 inside the body 2. The nitrate ion responsive film 3 contains a chloride ion capturing agent 4.;COPYRIGHT: (C)2003,JPO
