Description
アニオン性ポリマーとしてポリアクリル酸ナトリウムを5,10,15,20mg/Lそれぞれ含むようにした検水を測定セル(ポリスチレン製、光路長10mm、光路幅10mm、高さ45mm、外幅12.5mm)に4mL採取した後、蓋をして数回振った。
ポリスチレン製、光路長10mm、光路幅10mm、高さ45mm、外幅12.5mmの測定セルにEDTA0.7重量%水溶液1.5mLを封入したセルを用いて測定を行った。セルの蓋を取り、比較例1とそれぞれ同一濃度のポリアクリル酸ナトリウム水溶液よりなる検水を1mL添加した後、塩化ベンゼトニウム5重量%水溶液を約20μLスポイトで滴下した。それ以外は比較例1と同様にして測定を行い、測定装置指示値とポリアクリル酸ナトリウム濃度とをグラフにプロットして検量線を作成した。結果を図1に示す。
