The SEM-EDS microanalysis revealed a differential deposition of copper on the zinc-reinforced as well as the bare part of the zeolite pellets. The top three highest amounts of post-treatment copper deposition were detected as follows: 17.1 % weight pertaining to the pellet core as per the treatment (ZnGZ-M-F), followed by 7.65% weight pertaining to the zinc-coated area of the pellet of the treatment (ZnGZ-M-F), then 5.1% of
