Description
ため、冬季など周囲の温度が5〜10℃付近まで下がると、薬液内で呈色試薬が結晶化することによって、薬液の供給経路などに詰まりを生じさせ、呈色試薬の添加工程において、所定量の薬液を正常に被測定水へ添加できなくなると云う問題があった。また、所定量の薬液を被測定水へ添加できたとしても、薬液中の呈色試薬の濃度に変化が生じているため、測定の信頼性を欠くと云う問題があった。
−ビス(2−スルホエチル)−3,3’−ジメチルベンジジン;N,N’−ビス(3−スルホプロピル)−3,3’−ジメチルベンジジン;N,N’−ビス(2−ヒドロキシ−2−スルホエチル)−3,3’−ジメチルベンジジン;N,N’−ビス(2−ヒドロキシ−3−スルホプロピル)−3,3’−ジメチルベンジジン;N,N’−ビス(4−スルホブチル)−3,3’−ジメチルベンジジン;N,N’−ビス(3−スルホプロピル)−N,N’−ジエチル−3,3’−ジメチルベンジジン;N,N’−ビス(2,4−ジスルホベンジル)−3,3’−ジメチルベンジジンおよびこれらのアルカリ金属塩などが挙げられる。これらの化合物のうち、ナトリウム塩の形態のものは、水溶性が高く、常温で結晶化が起こりにくいため、とくに好適に利用することができる。
に応じて、界面活性剤を含有させることができる。この界面活性剤としては、臨界ミセル濃度(CMC)が相対的に低く、また被測定水中の有機物と結合して不溶性の懸濁物を生じさせない観点から、非イオン性界面活性剤または陰イオン性界面活性剤が好ましく用いられる。利用可能な非イオン性界面活性剤としては、たとえばポリオキシエチレンアルキルエーテル,ポリアルキレンアルキルエーテルおよびポリオキシエチレンジスチレン化フェニルエーテルなどのほか、高級アルコール系非イオン性界面活性剤が挙げられる。また、利用可能な陰イオン性界面活性剤としては、アルキルジフェニルエーテルスルホン酸塩などが挙げられる。
呈色試薬としてN,N’−ビス(2−ヒドロキシ−3−スルホプロピル)−3,3’−ジメチルベンジジン二ナトリウム塩(株式会社同仁化学研究所;商品名「SAT−3」)を用い、表1に示す配合割合で各種の成分を混合して一液型の薬液を調製した。表1において、界面活性剤は、高級アルコール系非イオン性界面活性剤(三洋化成工業株式会社;商品名「ナロアクティーHN−100」)を使用した。つぎに、各比較例の薬液100ミ
リリットルを温度5℃に設定した冷蔵庫内で保存し、2日,7日,15日,30日,45日および60日経過後における結晶化物の有無を調べた。結果を表2に示す。
呈色試薬としてN,N’−ビス(2−ヒドロキシ−3−スルホプロピル)−3,3’−ジメチルベンジジン二ナトリウム塩(株式会社同仁化学研究所;商品名「SAT−3」)を用い、表3に示す配合割合で各種の成分を混合して一液型の薬液を調製した。表3において、界面活性剤は、高級アルコール系非イオン性界面活性剤(三洋化成工業株式会社;商品名「ナロアクティーHN−100」)を使用した。つぎに、各実施例の薬液100ミリリットルを温度5℃に設定した冷蔵庫内で保存し、2日,7日,15日,30日,45日および60日経過後における結晶化物の有無を調べた。結果を表4に示す。
表2によれば、アルコール化合物を呈色試薬の0〜15重量倍含むように調製された各薬液は、5℃の温度条件において、2〜14日の短期間で呈色試薬の結晶化物が生成した。一方、表4によれば、アルコール化合物を呈色試薬の20〜40重量倍含むように調製された各薬液は、5℃の温度条件において、60日経過時点で、いずれも結晶化物の生成が見られなかった。したがって、薬液中にアルコール化合物を呈色試薬の20重量倍以上含有させた場合、呈色試薬の結晶化を長期的に防止できることがわかる。
