A Novel Analytical Method of Thallium Determination in Gold Electrodeposition

Thallium is used in both cyanide and sulfite-based gold plating bath solutions as an additive that modulates how deposits on the target substrate. The level of Tl has a large effect properties being deposited, including its microstructure hardness. Thus, especially commercial process applications, it critical to be able measure content accurately, quickly, facilely order ensure proper quality products manufactured. cyclic voltametric behavior Tl-containing been investigated, but quantification unsatisfactory, either expensive time consuming, or not accurate complexed matrices. Here, we present proprietary, electroanalytical method measurement fast gives excellent accuracy sensitivity, even presence common breakdown products.
