• used for the synthesis of Cu2O NPs with different sizes, it is not used in the degradation of MP. Methyl parathion degradation The degradation of MP was achieved in deionized water by reacting MP with Cu2O NPs in a 1:5 molar ratio. This was carried out using 250 mL of a 1.5 × 10−4 M aqueous solution of

• strength, some calcined hydrotalcites can catalyze the transformation of MP to p-nitrophenol (p-NP) and retain its by-products. Such a process has the advantage of being able to be carried out at room temperature and at the pH of the pesticide solution. Keywords: basicity; hydrotalcite; methyl parathion

• degradation; mixed oxide; organophosphate; pesticide; water pollution; Introduction MP, an organophosphate, has been extensively used as pesticide since the 1970’s instead of chlorinated hydrocarbons (e.g., DDT). This pesticide is persistent and very toxic to humans and animals [1], even at low
