تقدير عنصر الكروم في المواد البايولوجية باستخدام تقنية مطيافية الانبعاث الذري-بلازما الحث المقرن ICP AES

الملخص EN

Many concentrated acids or their mixtures were used to compelet the digestion of the certified reference material type(MA-A1) which was used for the determination of chromium in it using Inductively Coupled Plasma-Atomic Emission Spectroscopy (ICP/AES).

It was found that the mixture (HClO4:H2O2)(1:1) was to be the best for chromium determination with recovery of (98.19) % and (HCl:H2O)(1:1) as a second proper acid for chromium analysis .This method was applied on twenty tissue samples of patients with breast tumors aged (15-60) years to determine chromium concentration .

Chromium concentrations in sera samples of the same patients were also measured and deficiency in chromium concentration values were appeared in sera of patients with breast cancer compared with benign cases.
