A new and sensitive method for trace copper control in foods and culinary samples in copper pots

A preconcentration method was developed by using a Geleh Sar Shor clay as a new natural adsorbent material in solid phase extraction for thedetermination of copper ions in some foods and inculinary samples. The optimization of batch experimental conditions was performed. The Cuconcentrations was freed in Copper containers arecovered with tin, in the culinary samples were found
