Özet
Bu çalışmada lehimde kurşun tayini için yeni bir titrant kullanılmaya çalışılmış ve titrant olarak piromelitik asit seçilmiştir. Tayinler, pH 3,5\' ta, 25ºC sabit sıcaklıkta yapılmış, ortamın iyonik şiddeti sodyum nitrat ile ayarlanmıştır. Üç standart numune ve ticari bir lehim numunesinde yapılan kurşun tayinleri ile ilgili sonuçlar, bu titrantın kalay ve antimon içeren numunelerde kurşunun yüksek bir doğrulukla tayin edilebileceğini göstermiştir. Ayrıca kurşunun titrasyonu için piromellitik asitin sülfürik asitten daha iyi bir titrant olduğu belirlenmiştir. Sonuçlar atomik absorpsiyon spektrofotometresi ile elde edilen sonuçlarla karşılaştırılmış ve sonuçların uyum içinde olduğu görülmüştür.
