Description
ポリカルボン酸類とイソチアゾロン類とを純水に加えて、両水処理用薬品濃度を変えて一連の試料水を調製した。これらは、ポリカルボン酸類濃度が７．９ｐｐｍ（Ａ−１が２．２ｐｐｍ、Ａ−２が５．７ｐｐｍ）、イソチアゾロン類濃度が０．４３８ｐｐｍの試料水、ポリカルボン酸類濃度が１５．８ｐｐｍ（Ａ−１が４．４ｐｐｍ、Ａ−２が１１．４ｐｐｍ）、イソチアゾロン類濃度が０．８６５ｐｐｍの試料水、ポリカルボン酸類濃度が３１．６ｐｐｍ（Ａ−１が８．８ｐｐｍ、Ａ−２が２２．８ｐｐｍ）、イソチアゾロン類濃度が１．７５ｐｐｍの試料水であった。また、参照試料水として、純水の他に、上記の各試料水と同じポリカルボン酸類濃度のポリカルボン酸のみを含む一連の試料水、および、上記の各試料水と同じイソチアゾロン類濃度のイソチアゾロン類のみを含む一連の試料水も純水を用いて調製した。 Adding the polycarboxylic acid and isothiazolones in pure water to prepare a series of water sample by changing both water treatment chemical concentration. These were sample water having a polycarboxylic acid concentration of 7.9 ppm (A-1 was 2.2 ppm and A-2 was 5.7 ppm), an isothiazolone concentration was 0.438 ppm, and a polycarboxylic acid concentration was 15.8 ppm (A -1 is 4.4 ppm, A-2 is 11.4 ppm), the sample water has an isothiazolone concentration of 0.865 ppm, and the polycarboxylic acid concentration is 31.6 ppm (A-1 is 8.8 ppm, A-2 is 22.2 ppm). 8 ppm), and the sample water had an isothiazolone concentration of 1.75 ppm. In addition, as a reference sample water, in addition to pure water, a series of sample waters containing only polycarboxylic acids having the same polycarboxylic acid concentration as each of the above sample waters, and isothiazolone having the same isothiazolone concentration as each of the above sample waters A series of sample waters containing only water was also prepared using pure water.
インジェクター３から各試料水を１００μＬ（マイクロリットル、以下同様）ずつキャリア液中に注入し、試料酸化反応器５にて酸化処理を施した後、混合器６に導入した。 100 μL (microliter, the same applies hereinafter) of each sample water was injected from the injector 3 into the carrier liquid by 100 μL (microliter, the same applies hereinafter) .
