Abstract:
In this work, waste chicken eggshell was applied as precursors for the preparation of copper-calcium
hydroxide nitrate (CuCa HN), a wet air oxidation catalyst, in the degradation of methyl orange (MO) dye from
water. Chicken eggshell was calcined for 4 hours at varying temperatures, 750 ℃-1050 ℃, to obtain bio-CaO.
The CuCa HN catalysts were hydrothermally heated in 30 minutes assisted with metal oxide method, at the
control molar ratio of Cu: Ca as 4:1. The physicochemical, structural and surface properties of bio-CaO and
catalysts were investigated. The catalytic performance of the catalysts was evaluated in degradation of MO,
through catalytic wet air oxidation process under ambient conditions, using 500 ppm of MO, and 2 g/L of
catalyst loading. The results showed that the optimum calcination temperature of 900 ℃ gave a relatively high
specific surface area of bio-CaO (21.10 m2g-1) and relatively smaller particle size (747 nm). All CuCa HN
materials showed ~100% color removal efficiencies of MO and >90% COD removal efficiencies within
5 minutes. The waste chicken eggshell is of high potential to be utilized as a raw material to produce effective
and reusable CuCa HN catalysts for the treatment of wastewater
