Chlorine disinfection of secondary wastewater effluent and drinking water can result in the production of the potent carcinogen N-Nitrosodimethylamine(NDMA) at the lower concentration ranges. Because of increasing concern of presence of NDMA in water, effective analytical method to determine NDMA should be developed. In this study, we have investigated to determine optimal condition for the analysis of NDMA using a statistical methodology. The existing single-dimentional search is laborious, time consuming, and incapable of reaching the true optimum due to neglecting of the interaction among variables. to resolve this problem, RSM(Response Surface Method) has been proposed to determine the individual factors and their interactive influence. RSM is a statistical technique for designing experiment, building models, evaluating the effects of several factors and searching optimum conditions for desirable responses and reducing number of experiments. The analysis of NDMA and by-products using SPME(Solid Phase Micro-extraction) technique with GC-FID.
