Abstract :

Most of the analysis time is spent in sample preparation. Therefore, the need to improve sample preparation techniques is increasingly noted. One of the oldest and most widely used methods in this field is liquid- liquid extraction solid phase extraction (SPE) is a popular alternative to liquid- liquid extraction and its popularity and application is increasing rapidly. Ionic imprinted polymers are synthetic materials that detect the target molecule by simulating its structure .Ionic imprinting method has been used to eliminate disturbance and concentrate the samples. Ionic imprinted polymers have tremendous benefits such as pre-set selection, as well as being easy and convenient to prepare. Hence, these materials are now increasingly used as sorbent in solid phase extraction. In this research, a selective ionic imprinted polymer for calcium ions has been prepared using ion printing method. Experimental conditions have been investigated and the IIP used as an effective and selective adsorbent for the solid phase extraction of calcium.
