Application of diphenylcarbazone_Kain Industrial Additives

background and overview[1][2] diphenylcarbazone (dpc) is an important organic analytical reagent. it can form blue, purple, and red chelates with many heavy metal ions, so it is widely used to determine heavy metal ions such as cr (iv), chromogenic reagents or photometric reagents for hg (ii), mo(vi), cu(ii), etc. because the chromogenic system of diphenylcarbazone has the advantages of high sensitivity, good reproducibility, and accuracy, it…
