- •
In this method, 2-mercaptobenzimidazole(MBI) was used as a chelating agent, which formed a stable and hydrophobic complex with palladium(II) ions.
- •
The reaction between Pd(II) and MBI is very fast.
- •
2-mercaptobenzimidazole(MBI) is a selective reagent for Pd(II); thus, the DLLME has good selectivity.
- •
The developed method is a selective, rapid, sensitive, and an environmentally friendly method for ultra-trace analysis of Pd.
