Gram-negative bacteria are an increasingly serious source of antibiotic-resistant infections, partly owing to their characteristic protective envelope. This complex, 20 nm thick barrier includes a highly impermeable, asymmetric bilayer outer membrane (OM), which plays a pivotal role in resisting antibacterial chemotherapy. Nevertheless, the OM molecular structure and its dynamics are poorly und...

Synthetic dyes are extensively used in many industrial applications like textile, leather and cosmetics. The release of various harmful dyes from these industries into the environment has attracted great attention worldwide in recent years. Biosorption is a very effective dye removal technique from aqueous system. In this research, the biosorption performance of cone of red pine for C.I. Basic ...

The adsorption studies of phenol from aqueous solution on allium sativum peel have been studied in the range of 50-250 mg/L initial phenol concentration .The study was carried out as function of contact time, pH, initial phenol concentration,allium sativum Linn peel dosage and temperature. The experiment demonstrated the maximum phenol was obtained at in pH of 2 and it takes 6h to attain equili...

ABSTRACT: Activated carbon was developed from coconut shell, characterized and used for the removal of Rhodamine-B from wastewater successfully. The methylene blue number, iodine number and BET surface area of the prepared carbon were found to be 80 mg g, 600 mg g, and 1200 m g respectively. Rhodamine B is one of the water soluble, basic red cationic xanthene class dyes, a common water tracer f...

The surface adsorption of heavy metals in effluents with nanoparticles is today asuitable method for effluents treatment. In the present study, lignocellulose nano-fibers(LCNFs) were used as natural adsorbent for lead adsorption. The aim was to evaluate leadadsorption using adsorption isotherms, kinetics and thermodynamics. Fourier TransformInfrared Sp...

abstractin this work, the micro powder was the product of cedar leaf (mpcl) is used as a low-cost adsorbent for the removal of pb2+ ions from aqueous solutions. bath experiments were used to determine the best adsorption conditions the adsorption percentage of pb2+ ions mpcl samples at different initial ph, contact time (tc), adsorbent dosage and temperature (t) were investigated. effective rem...

in the present work, we have investigated the sorption efficiency of the treated activated carbon from walnut shell(acw) towards direct red 81 (dr81) and direct blue 71 (db71) for the removal from aqueous solution. thesorption study of acw at the solid-liquid interface was investigated using kinetic, sorption isotherms, ph effectand amount of adsorbent. experimental data were analyzed by langmu...

malicorium supported ni0.5zn0.5fe2o4 magnetic nanoparticles were synthesized by a low-cost, simple,and environmentally benign procedure. the adsorbent was characterized by several methods includingx-ray diffraction (xrd), scanning electron microscopy (sem) and fourier transform infraredspectroscopy (ft-ir). then, the potential of malicorium supported ni0.5zn0.5fe2o4 magneticnanoparticles was in...
