The Microdetermination of Biological Copper with Oxalyldihydrazide.

Ziziphus mauritiana mediated synthesis of copper and nickel nanoparticles for comparative efficacy in biological water purification

The burden of life on the earth is the source of biological contamination in water. Nanotechnology has promising contributions in control of microbial contaminations and medicinal plants further increase these properties. Presently, copper acetate and nickel oxide nanoparticles were synthesized using 1mM solution of each with Ziziphus mauritiana leaves extract as reducing agent. Nanoparticles w...

Colorimetric Microdetermination of Free Fatty Acids1

A colorimetric method for determination of free fatty acids has been developed, based on the estimation of copper in a chloroform extract of their cupric salts with oxalic acid bis-(cyclohexylidenehydrazide). Contamination with inorganic copper during extraction is practically eliminated by using filter-paper pads. Specificity and interferences are discussed. Recoveries average 101.1%. Normal v...

Photoelectric Microdetermination of Chloride in Biological Fluids, and of Iodate and Iodine in Protein-free Solutions

Hybrid Nanocomposites of Montmorillonite/Copper Oxide, Synthesis and Evaluation as Effective Growth Inhibitors in Different Biological Systems

The external and interlamellar spaces of montmorilonite (MMT) were used as solid support for synthesis of CuO nanoparticles (NPs) at room temperature by the chemical reduction method. In this project, Copper Nitrate plus water (Cu(NO3)2. xH2O) and Sodium Hydroxide (NaOH) were used as Copper precursor and reducing agent respectively. Then, MMT/Cu2+ nanocomposites were stabilized with different r...
