Multiple Standard Addition and ISE Determination of Iodine Sea Food

Abstract

Abstract: The multiple standard addition method has been used in determinatiom of iodine ion in ISE linear response range. Assayin multiple standard addition has provided enough data for resolution of nonlinear equations.Through least squares and iterationmethod, the response slope of electrode and iodine ion concentration of sample solution could be calculated rapidly by computer.

Key words: multiple standrd addition, ISE, determination iodine ion, computer calculation
