| titleOfInvention | The method of Zn in the Fast Measurement aluminium alloy of a kind of stokehold |
| abstract | The invention belongs to the chemistry in detecting technical field of metallic element, in order to can fast effectively, the content of Zn accurately and in the mensuration aluminium alloy of low cost, provide the method for Zn in the Fast Measurement aluminium alloy of a kind of stokehold.Sample dissolves through nitration mixture, with sodium fluoride complexing Fen 3+ , Aln 3+ , thiocarbamide shelters copper ion, reduces impurity element to the interference measured; Add the Acidity of Aikalinity of hexamethylene tetramine to solution to cushion; Make indicator with xylenol orange, with the titration of EDTA standard solution, according to titration volumes, calculate the percentage composition of Zn, measure and get its mean value 3 times.The method of the invention can the content of Zn in Accurate Determining aluminium alloy; Detection time is 15min, has saved half the time than the minute 30min of GB (GB/T20975.8-2008) method one, and therefore the method for the invention is also suitable for the express-analysis carrying out stokehold, and device therefor is simple, convenient, and cost is low. |
