synthesis of the novel zeolite nay/cufe₂o₄ /cds ternary nanocomposite for the sonocatalytic degradation of toxic organophosphorus pesticide from water media

in this research, the zeolite nay/cufe₂o₄/cds ternary nanocomposite as a novel magnetically separable catalyst was successfully synthesized by means of the ultrasonic-assisted solvothermal strategy. the structural, morphological and optical features of the nanocomposite were analyzed by using fesem, edax, ftir, xrd and vsm. the sonocatalytic activity of zeolite nay/cufe₂o₄/cds was evaluated in the degradation of the toxic organophosphorus pesticide, namely chlorpyrifos (cp, o,o-diethyl o-3,5,6-trichloropyridin-2-yl phosphorothioate) from water media. several analytical parameters such as irradiation time, initial cp concentration, process type, catalyst dosage, and initial h₂o₂ concentration were investigated to achieve the maximum sonocatalytic performance. regarding the obtained data, the nay/cufe₂o₄/cds sonocatalyst was incredibly able to completely degrade the cp pesticide using the ultrasonic (us)/h₂o₂ system. the ˙oh free radicals were also recognized as the main reactive oxygen species on the sonodegradation reaction of cp under irradiation. moreover, the recyclability of the nay/cufe₂o₄/cds zeolite sonocatalyst was implemented, which clearly confirmed that it can be recycled up to sequential four times with almost trivial loss of sonocatalytic performance.
