This work deals with the synthesis of ZnFe2O4 NPs and studies effect addition on physical properties PVDF/PVC blend. XRD affirmed formation HRTEM shows that size prepared ranged from 20 to 55 nm. The behavior was studied through XRD, ATR-FTIR, FESEM UV–Visible spectroscopy. revealed enhanced crystallinity blend system also confirmed incorporation by appearing a diffraction peak at 2θ equals 35°...

introduction: arsenic is known as a carcinogenic compound in drinking water . it can cause acute and chronic effects on human health. in this study, the effect of polyamidoamine dendrimer generation 3(pamam g3) as adsorbents for removal of arsenic (v) from aqueous solutions was evaluated.     methods: adsorption experiment was studied in batch system and the effect of different variables like p...

abstractin this work, the micro powder was the product of cedar leaf (mpcl) is used as a low-cost adsorbent for the removal of pb2+ ions from aqueous solutions. bath experiments were used to determine the best adsorption conditions the adsorption percentage of pb2+ ions mpcl samples at different initial ph, contact time (tc), adsorbent dosage and temperature (t) were investigated. effective rem...

the interaction between some heavy metal ions such as of pb(ii), cd(ii) and cu(ii) ions from aqueous solution adsorbed by single walled carbon nanotube (swcnts) and carboxylate group functionalized single walled carbon nanotube (swcnt-cooh) surfaces were studied by atomic absorption spectroscopy. the effect of contact time, ph, initial concentration of ion, ionic strength and temperature on the...

In this article, a complex nature structure is simulated by introducing the nanofluid that contains various shape of nanoparticles through forced convection and thermal diffusion. Double sided lid-driven in porous curved cavity dealt to handle phenomenon. Additionally, effect internal heat generation/absorption also considered. The horizontal vertical walls are moving with constant speed Uo Vo,...

A highly sensitive technique based on optical absorption using a single-mode, channel integrated optical waveguide is described for broad spectral band detection and analysis of heme-containing protein films at a glass/water interface. Fabrication steps and device characteristics of optical waveguides suitable for operation in the wavelength range of 400 - 650 nm are described. Experimental res...

Abstract: Heavy metal contamination of drinking water poses serious threat to public health and ecosystems. Chronic exposure to such metal contamination can lead to various health problems including nerve and organ damages. Thus, removal of heavy toxic metals from the contaminated water supply is a critical issue of water quality management. Naturally-occurring resources have been attractive ca...

The characteristics of ion transport to the shoots of young corn seedlings were studied with respect to the nature of the isotherm through a wide concentration range, the competitive influence of closely related ions upon the transport of a given ion, and the influence of the counter-ion. Both with respect to (36)Cl and (86)Rb transport, the characteristics of the process in every way resemble ...
