Determination of inorganic ions in fertilizer industry wastewater by ion chromatographyhy

The aim of this work is development of methodology for analysis of inorganic cations (sodium, ammonium, potassium, magnesium and calcium) in fertilizer industry wastewater. Method development includes optimization of eluent flow rate and concentration of eluent competing ion in order to obtain optimal separation within reasonable analysis time. For that purpose artificial neural network retention model was developed and used in combination with normalized resolution product criteria function. Developed artificial neural network retention model shows good predictive ability R2 ‡ 0.9983. The determined ion chromatographic parameters enable baseline separation of all components of interest. By performing validation procedure and number of statistical tests it is shown that developed ion chromatographic method has superior performance characteristic: linearity R2 ‡ 0.9984, recovery = 99.81% - 99.44%, repeatability RSD £ 0.52%. That result proves that proposed method can be used for routine monitoring analysis in fertilizer industry.
