 The study examined the effects of different chelators on the environmental friendliness of electrolys deposition baths. It found that the presence of certain hydroxides affected the amount of copper deposited onto the substrates, while other additives such as DMAB, N-methyl thyria, and cytosine had no significant impact. Additionally, the presence of potassium hydroxide as a pH adjuster allowed for the deposition of higher amounts of copper than without it. Finally, the study also showed that the use of polyhydroxides, glycerol, and sorbitol as chelators resulted in more uniform coatings compared to when only one type of chelator was used.
