The biosorbent was obtained from municipal solid waste (MSW) of the Mostaganem city. Before use the MSW was dried in air for three days and washed several times. The sorption of yellow procion reactive dye MX-3R onto biomass from aqueous solution was investigated as function of pH, contact time and temperature. The adsorption capacity of MX-3R was 45.84 mg/g at pH 2-3 and room temperature. MX-3...

Struma ovarii is a specialized ovarian teratoma composed predominantly of mature thyroid tissue. It is associated with pleural effusion and ascites (Pseudo-Meigs’ syndrome) in 5% of cases. Majorities of the strumas are benign, however occasionally malignant transformation may be seen. We report a case of a 45 years old postmenopausal woman who presented with gradually increasing dyspnoea and di...

Novel biosorbent 'maize bran' has been successfully utilized for the removal of Cr(VI) from aqueous solution. The effect of different parameters such as contact time, sorbate concentration, pH of the medium and temperature were investigated and maximum uptake of Cr(VI) was 312.52 (mgg(-1)) at pH 2.0, initial Cr(VI) concentration of 200mgL(-1) and temperature of 40 degrees C. Effect of pH showed...

Pomegranate peel waste (PPW), a solid waste, was prepared and tested as biosorbent for the removal of a cationic dye, methylene blue (MB), from aqueous solutions by batch procedure. The effects of pH of solution, biosorbent dosage, contact time, and dye initial concentration on biosorption capacity were studied. MB uptake was favorable at pHs ranging from 5.0 to 12.0. The contact time required ...

BACKGROUND Struma ovarii is a rare ovarian neoplasm that often appears malignant on conventional imaging. Pseudo-Meigs' syndrome with ascites, pleural effusion, and elevated serum CA 125 levels is much rarer and leads to misdiagnosis of ovarian cancer and unnecessary extended surgery. CASE PRESENTATION A 50-year-old woman with abdominal distention and dyspnoea was referred to our hospital. Ul...

Biosorption characteristics of Pb(II) ions from aqueous solution were studied using some residues of solvent-extracted Otostegia persica known as goldar residue biomass. The effects of contact time (0–120 min), the initial pH 3–8, biomass dosage (0.53–2.6 g/L) and the initial lead concentration (5–25 mg/L) on biosorption were investigated. The maximum adsorption capacity of 17.3 mg/g at pH 5.5,...

Polydisperse brushes obtained by reversible radical chain polymerization reaction onto a solid substrate with surface-attached initiators, are studied by means of an off-lattice Monte Carlo algorithm of living polymers (LP). Various properties of such brushes, like the average chain length and the conformational orientation of the polymers, or the force exerted by the brush on the opposite cont...

Sesame leaf, an agricultural solid waste, was used as low cost adsorbent for removal of Pb(II) from aqueous solution in batch mode. The biosorbent was characterized by thermo-gravimetric analysis and Fourier transform infrared spectroscopy. The influences of phase contact time, solution pH, adsorbent dosage, and initial concentrations were investigated to optimize the conditions for maximum ads...
