Description
This Standard provides you with the principle of the polarographic method in which the sample is dissolved in hydrochloric acid and zinc is separated from other elements by absorption onto an anion exchange resin from a 2N hydrochloric acid solution.
Zinc is removed from the resin with N/200 hydrochloric acid and determined either volumetrically with EDTA or polarographically.
This method is recommended for zinc contents between 0.01 and 0.25 %, and the volumetric method for zinc contents between 0.10 and 12.0 %.
Overall, BS 1728-18 exemplifies zinc using polarographic for the analysis of aluminium and aluminium alloys.
