Spectrophotometric determination of Chromium(III) in Egyptian ilmenite from phosphate solution using Egyptian white sand (EWS) as a selective adsorbent

Egyptian white sand (EWS) was used as an adsorbent for the selective separation of Cr(III) from phosphate solutions which is to be determined colorimetrically using 1,5-diphenylcarbazide. The experimental factors affecting the maximum selective adsorption/desorption of Cr(III) on/from EWS where the amount of adsorbent (g), pH of initial concentration of Cr(III) in solution, contact time, temperature and initial...

Separation and determination of trace amounts of Pb(II)ions in water samples using organic solution-processable functionalized-nano graphene

A novel and selective method for the fast determination of trace amounts of Pb(II) ions in water samples has been developed. The first organic solution-processable functionalized-nano graphene (SPFGraphene) hybrid material with porphyrin–graphene nanohybrid, 5-4 (aminophenyl)-10, 15, 20-triphenyl porphyrin and its photophysical properties including optical triphenyl porphyrin (TPP) and grapheme oxide molecules...

Chemical constituents and anti-tuberculosis activity of the root extracts of Cissampelos owariensis (P. Beauv.) Menispermaceae

Extractives from the root of Cissampelos owariensis, were screened for antimicrobial activity against Staphylococcus aureus, Streptococcus pyogenes, Escherichia coli, Salmonella typhi, Pseudomonas aeruginosa, and Candida albicans. The crude methanol extract was found to be active against the test organisms except S. pyogenes and P.aeruginosa. The crude extract...

Synthesis of cholesteryl-(3,4-dihydroxy-5-methoxy tetrahydro-furan-2-yl) methanone

Various biological membranes are synthesized from sugars-based compounds. The hydrophobic groups of them made up the amphiphilic properties in the structure of membrane that consisted fatty acids, and long chain alkyl groups. It had established that cholesterol was an integral component and it affects the fluidity of membranes. We prepared the cholesteryl-(3, 4-dihydroxy-5-methoxy-tetrahydro-furan-2-yl)-methanone from...

Physicochemical properties and rheological behaviour of Ficus glumosa gum in aqueous solution

The physicochemical properties, cationic composition and rheological behaviour of exudates from Ficus glumosa were investigated. The gum was found to be mild acidic, ionic and soluble in water, sparingly soluble in ethanoland insoluble in acetone and chloroform. The trend for the decreasing concentration of elements determined in the gum sample is Mg > Ca > Mn > Zn > Fe > Ni > Zn...
