A simple analytical method was developed for determination of chloride content in polymeric materials. The procedure comprises of two steps, the dissolution of the polymer by alkaline fusion followed by indirect spectrophotometric analysis of the chloride based on the absorption at 460 nm of Fe(SCN)2+, a product of the reaction between chloride ion and a mixture of mercury (II) thiocyante and ferric ion. A non-linear calibration curve was constructed from 0.5 to 20 ppm with R2 = 0.9991; thedoi:10.32508/stdj.v18i2.1177 fatcat:6ux7jyycdvhlxkdz5sgxy2x5b4
