Heavy metal contents of bootee leathers tanned wıth different process recipes

Bebek patiği üretiminde kullanılan derilerdeki selenyum, civa, kurşun, krom, kadmiyum, baryum, arsenik ve antimon gibi ağır metal içeriklerinin belirlenerek elde edilen sonuçların deri ve tekstillere ait limit değerler ile karşılaştırılması bu çalışmanın amacını oluşturmaktadır. Mamul derilerdeki ağır metal içeriğinin çoğunlukla işlentide kullanılmış olan kimyasallara bağlı olduğu sonucuna varılmıştır. Özellikle, krom içeriğinin oldukça yüksek olduğu tespit edilmiştir. Diğer taraftan, boyama ve finisaj işlemleri sırasında meydana gelen kimyasal ve fiziksel reaksiyonlar sonucu ortaya çıkan selenyum, civa, kurşun, kadmiyum, baryum, arsenik ve antimon içeriğinin ise daha düşük miktarlarda olduğu belirlenmiştir.

Farklı işlenti reçeteleri ile tabaklanmış bebek patiği derilerinin ağır metal içerikleri

The purpose of this work was to determine the content of heavy metals such as antimony, arsenic, barium, cadmium, chromium, lead, mercury, selenium in leather used by producing baby bootees and to compare the limit values for leather and textiles. It was concluded that heavy metal content of finished leathers depended mainly on the chemicals used in processing; in particular, high chromium contents were determined. Moreover, small amounts of antimony, arsenic, barium, cadmium, lead, mercury and selenium deriving from chemical and physical reactions during dyeing and finishing processes were detected.
