The potential of nitric acid modified kola nut pod adsorbent (MKNP) in removing selected heavy metals such as lead (Pb2+), cobalt (Co2+), and cadmium (Cd2+) ions from aqueous solution was investigated. FTIR spectra before after the adsorption indicates presence functional groups hydroxyl carboxylic which are responsible for its surface chemistry. percentage removal largely depends on pH, contac...

The ninth component of complement (C9) polymerizes to tubules either spontaneously at a very slow rate (3 days at 37 degrees C) or within minutes if induced by C5b-8 as part of the membrane attack assembly (Tschopp, J., Podack, E. R., and Müller-Eberhard, H. J. (1984) J. Immunol., in press). The spontaneous formation of tubular sodium dodecyl sulfate-resistant C9 polymers was completely inhibit...

A pencil graphite electrode (PGE) was modified by the electropolymerization of pyrrole-1-carboxylic acid (Py-CO2) to form a sensing film poly(pyrrole-1-carboxylic acid) (PPy-CO2) for sensitive determination Pb2+ and Cd2+ differential pulse anodic stripping voltammetry (DPASV). The porous structure PPy-CO2 uniformly distributes carboxylate group throughout coating selectively coordinate preconce...

This study investigated the one-pot hydrothermal synthesis of mixed-phase ion-exchangers from waste amber container glass and three different aluminium sources (Si/Al = 2) in 4.5 M NaOH(aq) at 100 °C. Reaction products were characterised by X-ray diffraction analysis, Fourier transform infrared spectroscopy, 27Al 29Si magic angle spinning nuclear magnetic resonance spectroscopy scanning electro...

The synthesis of phytochelatins (PCs) is essential for the detoxification of nonessential metals and metalloids such as cadmium and arsenic in plants and a variety of other organisms. To our knowledge, no direct evidence for a role of PCs in essential metal homeostasis has been reported to date. Prompted by observations in Schizosaccharomyces pombe and Saccharomyces cerevisiae indicating a cont...

Three-dimensional (3D) urchin-like MnO2@poly (sodium 4-styrene sulfonate) (PSS)/poly (diallyl dimethylammonium chloride) (PDDA)/PSS particles were prepared via the layer-by-layer (LBL) assembly of polyelectrolytes for extraction Zn2+ from alkaline media. The adsorption performance on MnO2, MnO2@PSS/PDDA/PSS, and MnO2@(PSS/PDDA)3/PSS was investigated in batch experiments. MnO2@PSS/PDDA/PSS has b...

Purpose. The current study was conducted to evaluate the heavy metals adsorption and sorption rate when removing them from water processing it in Tigris River Samarra city, Salah El-deen, Iraq 20212022 efficiency of zeolite for metals, as well determine high low percentage all found river. Methodology. included analysis measurement physical chemical properties with low-cost natural no side effe...

Mesoporous silica materials (MSMs) of the MCM-41 type were rapidly synthesized by microwave heating using silica fume as silica source and evaluated as adsorbents for the removal of Cu2+, Pb2+, and Cd2+ from aqueous solutions. The effects of microwave heating times on the pore structure of the resulting MSMs were investigated as well as the effects of different acids which were employed to adju...
