An alternativecalibrationprocedure is the standard addition method as outlined at the beginning of the page. Example Calculation: The Fluoride Ion-Selective Electrode Two 10.0 ml aliquots are taken from a sample of wastewater effluent and one is spiked with 1.00 ml of 0.0207 M NaFstandard solution...
Some scientific analytical techniques are designed to find the amount of individual substances inside a mixture. At times this is straightforward, but some samples interfere with the ability of the technique to assess the trueconcentrationof a substance in a mixture. Standard addition is a way of ...
A method, called "K-Ratio H-Point Standar Addition Method", was proposed. At two different wavelengths, a K ratio was introduced to the regression equations of the absorbance against the concentrations of standard addition of the analytes to eliminate the interference, after calculating, the inters...

and compare the findings with data derived using the conventional method of relative quantification where values are interpolated from a standard curve. Our approach is based on the method of standard additions, a quantitative approach used in analytical chemistry where standards are spiked directly into...
not its slope. Notice that both styles of interference could have the same effect on the observed signal (point X); it takes observations at more than one concentration to distinguish between the two styles. It is not unusual for both effects to be present simultaneously, but the method of ...
