The content of burning additives in cigarette paper is important factor used for the cigarette design. Currently, COREASTA recommends enzymatic method for the determination of citrate content. In this study, we compared three different analytical methods for the determination of citrate content which are enzymatic method, electrical conductivity method and ion chromatography method. These are generally used for the analysis of burning additives. Advantages of electrical conductivity method include simplicity of determination and reduction of run times in comparison with enzymatic method. However, this method is generally less accurate than other methods. Ion chromatography method is available to simultaneously analysis of all anion used as burning additive and has very higher accuracy. In this study, we have analyzed two type of cigarette paper samples which are added to sodium citrate and potassium citrate as burning additives. Each type's burning additive has been applied to cigarette paper in 3 levels. We tested accuracy and precision, by analyzing these samples. Electrical conductivity method has higher citrate contents in all samples than other method. It seems that electrical conductivity method could be affected by other fillers in cigarette paper. Ion chromatography method has similar citrate contents to enzymatic method. Average recovery ranted between 100 % and 104 %, and RSDs of the recovery were below 2.0 %. Ion chromatography method exhibited excellent accuracy and precision. Moreover, ion chromatography method has the advantages of simple sample pre-treatment and simultaneous analysis. The refore, ion chromatography method might be the most effective method for the determination of burning additive.
