ANALYSIS OF THE FLOW CHEMISTRY.
The analysis of anions in drinking water has traditionally applied the environmental ion chromatography which has been gaining all the acceptance of the wastewater analysis. The anions analyzed are SO4, NO4, NO2, Bromine and also the chlorine. The detection limits suffer in case the samples end up having dissolved solids or even organics. All this is caused by the dilutions which can be of help when eliminating the interferences. The can be issues with the interferences when relating to the flow chemistry. The method of the flow chemistry can be able to analyze the solution directly without any dilution. However, the high concentration of the chloride interferes with the determination of the amounts of the Nitrite. Its also advisable for the samples of the nitrates to be preserved since they all require a high sulfate level of a sample dilution. The nitrates should be tested before 48hours are over, as they cannot be analyzed by the ion chromatography as well.
Sulfuric acid and flow methods are in terms while the fluoride only becomes in terms with the determination of the ion chromatography at any level above 1.0mgl. Deviations are always important from the procedures to be followed which are supposed to be followed. However, methods for P of the flow chemistry are always sensitive since the interferences become absent more often. The flow chemistry is also in a position whereby it can determine all forms of P in a solution. Sulfate which is always at low levels is however very difficult to determine in high chloride since the dilutions will bring the scales to be on responses. If any dilutions are not done with the samples, the high content in the salt brings retention which at times makes the sulfate to be identified as the phosphate from the data systems.
The ion chromatography is an excellent job and it also needs to have a detector with a separate column. The type of the detector is utilized by the flow chemistry methods and the other colors too. A way is always provided by the ion chromatography in which the determination of the drinking water and anions are unsurpassed in a method. Automated analysis can be allowed by the flow analysis as well since it can allow automated samples which at times becomes more difficult for the non-metals and anions as well. Flow chemistry can be done with the automation of extractions, distillations and also the digestion. Accurate level of the chloride can be prevented by high dilutions so as to be able to dilute copper, Aluminium,and also destroy the column of the ion chromatography. The samples of the nitrates cannot be preserved since the analysis and the high sulfate needs to have sample dilution.
