2)産業廃棄物・建材廃棄物の処理・処分前におけるロックウールの含有有無の判定、
3)各種のロックウールの含有が疑われる製品・器具・材料中におけるロックウールの使用有無の判定、
1)粉砕状態の試料を、有機酸の酸性水溶液に接触させて、試料付着金属成分を溶出させた後、固液分離後の試料を精製水で洗浄する前処理工程、
2)前記前処理工程後の試料を、非酸化性無機酸の酸性水溶液に接触させて判定成分を溶出させた後、該判定成分の溶出液を試料から分離して判定液とする判定液調製工程、
3)前記判定液に鉄分呈色試薬を添加し、呈色安定領域のpHにおいて、呈色の有無を判定する呈色判定工程、
の各工程をそれらの順に含むことを特徴とする。
この工程は、試料に付着している、ロックウール鉄成分以外の鉄成分(鉄錆、鉄化合物、土壌起源鉄成分等)さらには、判定呈色反応の阻害要因となるカルシウム成分等を除去するための工程である。
試料14として0.5〜2 cm3 、望ましくは、1cm3 前後(豆粒大)の量の大きさのものを小ビーカー等の試料容器12に入れる。ここで、試料を多く採りすぎると、最終判定に際して、判定液が濁ったり、黄色くなったりすることがある。
この工程は、試料中の判定成分を溶出させて、該判定成分の溶出液を試料から分離して判定液とする工程である。
上記判定液15に、鉄イオン(II)と特異的に反応する鉄分呈色試薬(キレート化剤:以下「呈色試薬」ということがある。)26を添加して、ロックウール鉄分をキレート化して、判定する工程である。
前処理液、溶解液、判定試薬、及び、pH調製剤(pH調整液)を、それぞれ下記の如く調製した。なお、使用した各薬剤は、特記していないものは特級試薬である。
約500mLの純水に酢酸(有機酸)200mLを加え混合した後、純水で1Lとした。
約500mLの純水にリン酸(無機酸)235mLを加え混合した後、純水で1Lとした。
4,7−ジフェニル−1,10−フェナントロリン(呈色試薬):400mgをエチルアルコール150mLに溶解し、HCl50mLを加えたのちに純水で1Lとした。
約500mLの純水に酢酸アンモニウム500gを加え溶解した後、純水で1Lとした。
<実施例1:ロックウールの判定>
1)豆粒大(約1cm3)の試料をビーカーに採る。
15 判定液(溶出液)
16 前処理液(有機酸の酸性水溶液)
24 脱脂綿(ろ材)
25 溶解液(非酸化性無機酸の酸化水溶液)
26 判定試薬(呈色試薬)
28 pH調整液
