Toxic effects of chlorpyrifos on morphology and acetylcholinesterase activity in the earthworm, Eisenia foetida

Autor: S.S. Madhavendra, J. Venkateswara Rao, Y. Surya Pavan

Publikováno v: Ecotoxicology and Environmental Safety. 54:296-301

The acute toxicity of chlorpyrifos (O, O-diethyl-O-(3,5,6-trichloro-2-pyridyl) phosphorothioate) was determined in the earthworm, Eisenia foetida. A 48-h contact test as described by the Organization for Economic Cooperation and Development (OECD) gu

Hydrodechlorination of chlorobenzene on Nb2O5-supported Pd catalysts Influence of microwave irradiation during preparation on the stability of the catalyst

Autor: S.S. Madhavendra, P.S. Sai Prasad, Shankar Narayanan, Rajesh Gopinath, G. Vivekanandan, K. Narasimha Rao

Publikováno v: Journal of Molecular Catalysis A: Chemical. 181:215-220

Catalytic hydrodechlorination of chlorobenzene was studied on Pd/Nb2O5 catalysts prepared by the conventional and the microwave heating techniques. The catalysts were characterized by X-ray diffraction (XRD), BET surface area, hydrogen chemisorption

Publikováno v: Journal of Materials Science. 32:965-969

Al2O3-supported 12 wt% V2O5 catalysts were prepared by physically grinding both the oxides (solid–solid wetting) and by wet impregnation techniques. The physical mixtures (PM) were treated under two different conditions – calcination in the prese

Hydrodechlorination of chlorobenzene over MgO MODIFIED Pt/Al2O3 CATALYSTS

Autor: S.T. Srinivas, P.S. Sai Prasad, S.S. Madhavendra, P. Kanta Rao

Al 2 O 3 was modified with MgO and was used as support in the preparation of platinum catalysts. The prepared catalysts were characterised by Scaning electron microscope (SEM), X-ray diffraction (XRD), chemisorption of H 2 and BET surface area and we
