Simultaneous Determination of Nickel (II) and Mercury(II) by Derivative Spectrophotometric Method
Mercury and nickel has overlapping absorbance spectrum area. Therefore the simultaneous analysis are difficult to perform. By using derivative spectrophotometry method, the analysis of both metals can be done without prior separation. Both metals can be analyzed quantitatively by the technique of ze...

Mercury and nickel has overlapping absorbance spectrum area. Therefore the simultaneous analysis are difficult to perform. By using derivative spectrophotometry method, the analysis of both metals can be done without prior separation. Both metals can be analyzed quantitatively by the technique of zero-crossing through complexation with DPC. Out of three derivative order value that has been obtained, the second derivative order gives the best analytical results, proven by a good precision (%CV) obtained 4,08% for nickel and 4,65% for mercury. Limits of detection and average percent for nickel are 0,050 ppm and 103.74%, while 0,035 ppm and 103.15% for mercury. |
