Two new chelating resins (o-HAP-DDE-HCHO and o-HAP-DDE-FFD), having multiple functional groups are synthesised by condensing the Schiff base of o-hydroxyacetophenone-4,4'-diaminodiphenylether (o-HAP-DDE) with formaldehyde and furfuraldehyde, respectively. The extent of loading of metal ions Cu(II) and Ni(II) was studied in both competitive and non-competitive conditions varying the time of cont...
A single-use electrochemical sensor using ionic liquid mediated hollow fiber-graphite working electrode was fabricated for the first time. The screening tool was developed by coupling this electrode with differential pulse voltammetry (DPV) for in-situ pre-concentration and determination of Zn(II) and Cu(II). In our plot, porous polypropylene hollow fiber membrane divided into pieces of 2 cm, t...
4(4-nitrophenyl-zao)-2-(2-methoxy phenimino)-phenol and its coordination compounds with ni(ii), cu(ii), co(ii) and fe(iii) have been synthesized and characterized by elemental analyses, ft-ir, far-ir, near ir, uv-vis, mass spectrometry and molar conductivity and their electrochemical behaviours are reported.
Nitrilotriacetic acid functionalized Adansonia digitata (NFAD) biosorbent has been synthesized using a simple and novel method. NFAD was characterized by X-ray Diffraction analysis technique (XRD), Scanning Electron Microscopy (SEM), Brunauer-Emmett-Teller (BET) surface area analyzer, Fourier Transform Infrared spectrometer (FTIR), particle size dispersion, zeta potential, elemental analysis (C...
Strong inhibition of uncoupled photosynthetic electron transport by Cu(2+) in isolated spinach chloroplasts was observed by measuring changes in O(2) concentration in the reaction medium. Inhibition was dependent not only on the concentration of the inhibitor, but also on the ratio of chlorophyll to inhibitor. Binding of Cu(2+) to the chloroplast membranes resulted in removal of Cu(2+) from sol...
We report thermal, X-ray diffraction (XRD) and cytotoxicity studies of complexes of fluconazole (FCZ) with Cu (II), Fe(II), Cd(II), Co(II), Ni(II), and Mn(II). From XRD measurements, FCZ and its metal complexes were identified as polycrystalline. Marked differences in the X-ray patterns of drug and its metal complexes revealed that the complexes are indeed different compounds and not just the m...

Ginkgo trees are common street trees in Korea, and the large amounts of leaves that fall onto the streets annually need to be cleaned and treated. Therefore, fallen gingko leaves have been used as a raw material to produce biochar for the removal of heavy metals from solutions. Gingko-leaf-derived biochar was produced under various carbonization temperatures and times. This study evaluated the ...
the adsorption ability of miswak (salvadora persica l.) waste was investigated for the removalof common heavy metals; pb(ii), cu(ii), ni(ii) and cd(ii), from aqueous systems. the miswak mainlyconsists of saponins, tannins, silica and resin, which are accounted for the removal of heavy metal ions fromaqueous systems. the effects of various parameters, such as solution ph, contact time, initial c...
