Creating a sustainable and effective approach to handling organic contaminants from industrial waste is an ongoing problem. In the present study, ZnO nanoparticles (ZnO NPs) were synthesized under a controlled ultrasound cavitation technique using the extract of Passiflora foetida fruit peels, which act as a reducing (i.e., reduction of metal salt) and stabilizing agent. The formation of monodispersed and hexagonal morphology (average size approximately 58 nm with BET surface area 30.83m2/g). The synthesized ZnO NPs were characterized by a various technique such as UV–visible spectroscopy, X-ray diffraction (XRD), Fourier-transform infrared (FTIR), Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), Transmission electron microscopy (TEM), Thermogravimetric analysis (TGA) and Dynamic light scattering (DLS). Further, the XRD pattern confirmed the hexagonal wurtzite structure of synthesized ZnONPs. The ZnO NPs exhibit excellent degradation efficiency towards organic pollutant dyes, i.e., Methylene blue (MB) (93.25% removal) and Rhodamine B (91.06% removal) in 70 min, under natural sunlight with apparent rate constant 0.0337 min−1 (R2 = 0.9749) and 0.0347 min−1 (R2 = 0.9026) respectively.Zeta potential study shows the presence of a negative charge on the surface of ZnO NPs. The use of green synthesized ZnO NPs is a good choice for wastewater treatment, given their high reusability and photocatalytic efficiency, along with adaptability to green synthesis.
Aim: The world's appetite for plastics is increasing by million tons every year. Alternative raw materials are needed in the polymer industry. Vidarikand is an extensive source of starch, having vast applications. Method: Extraction of starch involves various methods such as grinding, incubation, screening, sedimentation, washing, and drying. The application of starch in polymers shows an incredible future for industries. To find the effect of different starch sources on the synthesis and biodegradation of polymers. The content of starch extracted through vidarikand was found to be 81.51%. The films of starch: PVA blend was prepared using ultrasound cavitation technique followed by solvent casting method. Meanwhile, the biodegradable plastic films were prepared using potato and starch extracted from vidarikand tuber. The casted films were subject to various characterization techniques (TGA, SEM, FTIR, mechanical properties, soil burial, and solubility test). Result: Starch: PVA blends shows two decomposition position one is at 381 with second at 502°C with total weight loss of 79 and 98 %, respectively. PVA film of variable composition (starch from vidarikand) shows properties significantly more (soil burial-36.25%), solubility test-68.75%, elongation at break-34.3%, and tensile strength-6.92MPa) as compared to that of PVA film prepared using starch extracted from potato starch. Conclusion: The significant difference found in the degradation property of starch: PVA films from Vidarikand and potato starch. The prepared film of starch: PVA using starch extracted from vidarikarnd has significant applications in pharmaceuticals and packaging. Conclusion: The significant difference found in the degradation property of starch: PVA films from Vidarikand and potato starch. The prepared film of starch: PVA using starch extracted from vidarikarnd has significant applications in pharmaceuticals and packaging.
