FT-IR Spectra of (a) ZnO, (b) modified ZnO, (c) TritonX only and (d) Zinc Acetate Dihydrate from 350 to 4000 cm−1. Distinct peak of inorganic divalent metal oxide was seen below 500 cm−1 in both ZnO and modified ZnO. Comparative peaks were observed between Triton X-100 only and modified ZnO. Peaks corresponding to 1200–1600 cm−1 are of symmetrical and asymmetrical stretching of C=O bond which were found significantly reduced in synthesized particle with respect to Zinc Acetate Precursor. Also, 3500 cm−1 peak intensity for bonded −OH are significantly reduced conferring samples are of high purity
