Abstract
Description
本新規送達システム中の次亜塩素酸ナトリウムの持続性をヨウ素滴定によって決定した。本試験では、0.05gの新規送達システムを、1.0重量%酢酸を含有する40mL無水エタノールに分散する。1gのヨウ化カリウムを添加し、そして混合物をN2雰囲気下の室温で1時間撹拌する。放出されたヨウ素を、0.01モル/Lチオ硫酸ナトリウム水溶液で滴定する。同一手順を、対照としての同量の純粋な綿/ポリエステルブレンド織物に実施する。以下の式1によって、百分率の塩素含有量(次亜塩素酸ナトリウム含有量を示す)を算出した。
綿/ポリエステルブレンド織物(60/40)の断片(50cm×30cm)を、2gのポリエチレングリコールエポキシドおよび0.5gのメラミンを含有する水溶液100mlに1分間浸漬した。100%の収得(pick up)を得るために織物が埋め込まれ(padded)、次に、120℃で一定重量になるまで乾燥させた。室温まで織物を冷却した後、2%の次亜塩素酸ナトリウムを含有する水性アクリルコーティング/接着剤溶液5mlを織物上に噴霧し、次に、織物を一晩空気乾燥した。
他の実施例において、竹製織物(自然由来の竹から得られるビスコース100%から製造された編物)の断片(50cm×30cm)を、2%次亜塩素酸ナトリウムの10%水性アクリルコーティング/接着剤溶液を含有する水溶液100mlに浸漬し、100%湿潤ピックアップになるまでパッドした。この織物上に、2%水性ポリウレタンおよび1%エポキシド/メラミン樹脂を含有する水溶液5mlを噴霧した。この織物を、一定重量になるまで、真空下40℃で乾燥させた。ヨウ素滴定試験によって、この処理後、この織物が約580ppmの次亜塩素酸ナトリウムを含有していたことが示された。室温大気への2ヵ月の暴露後、約540ppmを超える次亜塩素酸ナトリウムが残存した。これは、最初に保持された次亜塩素酸ナトリウムの約90%超が残存したことを意味する。従って、この織物は、次亜塩素酸ナトリウムの貯蔵および送達のために使用可能である。
300〜1200μmの粒径および10nm(100Å)の平均細孔径を有するポリ(4−エチルスチレン−co−ジビニルベンゼン)多孔性ビーズ、10gを、10%次亜塩素酸ナトリウムを含有する次亜塩化ナトリウム水溶液500mLに添加した。1gのポリエチレングリコール(MW:5000)を混合物に添加し、混合物を室温で24時間撹拌し、次亜塩素酸ナトリウムを多孔性ビーズの細孔に吸着させた。ビーズを濾過によって回収し、一晩、暗条件下の真空デシケータ中で乾燥させた。これらのビーズは、次亜塩素酸ナトリウム含有ビーズとして定義される。
