Determination of chlorine content in refined palm oil

Chlorine always detected as the contaminant as it can cause plugging, fouling and corrosion in the pipeline and other equipment during processing of refined palm oil and higher chlorine content can cause trouble in human health. Thus, method of determination of chlorine content for water soluble chlorine sample and water insoluble chlorine sample in refined palm oil was important as the prevention acts using XRF, GC-MS and DPD colorimetric kits as testing method. Based on the testing method, GC-MS is very suitable for determination of higher organic chlorine content whereas XRF method was very easy to monitor the organic chlorine content in refined palm oil but the method for XRF is not complete as the unavailability of the standard. For wet chemical analysis method, the water soluble chlorine sample method is easiest to use to detect the inorganic chlorine content.
