Comparative study of different ultrasound based hybrid oxidation approaches for treatment of real effluent from coke oven plant.

The present study investigates the treatment of real coke plant effluent utilising several ultrasound-based hybrid oxidation approaches including Ultrasound (US) alone, US + catalyst, US + HO, US + Fenton, US + Ozone, and US + Peroxone, with main objective as maximizing the reduction of chemical oxygen demand (COD). Ultrasonic horn at power of 130 W, frequency as 20 kHz and duty cycle as 70% was applied. Study with varying catalyst (TiO) dose from 0.

Imbibitional redox and hormonal priming revealed regulation of oxidative window as a key factor for progression of germination of indica rice cultivars.

Unlabelled: In the present investigation we have manipulated seeds of two indica rice cultivars, differing in sensitivity towards salinity stress ( L. cv. IR29 and Pokkali), with different combination of germination influencing hormones and redox modulating agents [500 µM Gibberellic acid (GA) + 20 mM HO, 500 µM GA + 100 µM Diphenyleneiodonium chloride (DPI), 500 µM GA + 500 µM N,N-dimethylthiourea (DMTU), 30 µM Triadimefon (TDM) + 100 µM DPI, 30 µM TDM + 500 µM DMTU] during early imbibition for exploring significance of regulation of oxidative window during germination.

Sonochemical synthesis of Ce-TiO nanocatalyst and subsequent application for treatment of real textile industry effluent.

Treatment of real textile industry effluent using photocatalysis, sonocatalysis, sonophotocatalysis and HO assisted sonophotocatalysis have been studied based on the use of Ce-TiO nanocatalyst synthesized using sonochemical co-precipitation method. Characterization studies of the obtained catalyst revealed crystallite size as 1.44 nm with particles having spherical morphology.
