Aggregation Behavior of the Antibiotic Moenomycin A in Aqueous Solution
The aggregation behavior of the antibiotic moenomycin A (MoA) in aqueous solution under the influence of pH and ionic strength has been investigated using the fluorescent probe pyrene. Changes of the cmc between 0.03 and 0.7 mM correlate with the effective charge of MoA originating from three ionizable groups, the pKa of which have been determined by infrared spectroscopy. The dependence of the...
متن کاملInteractions of a hydrophobically modified polymer with oppositely charged surfactants.
The interaction of a hydrophobically modified anionic polymer (PMAOVE) with a cationic surfactant (DTAB) was studied using a multi-technique approach: turbidity, surface tension, and viscosity measurements, as well as EPR (5-doxyl stearic acid) and fluorescence (pyrene) probe techniques were used. In the investigated pH range (4-10), the cationic surfactant headgroups interact with the anionic ...
متن کاملChemical modified bark for Cu (II) sorption from aqueous solution
In present study the removal of Copper ions from aqueous solution containing 100-800 mg/lit, using chemically modified Acacia bark was performed on laboratory scale. The chemical modification was done by treating grinded bark with formaldehyde in acidic medium. The Cu (II) is exchanged against protons on the modified bark that contain carboxyl groups in both pectin and tannin compounds. The eff...
متن کاملAdsorption Efficiency of Iron Modified Carbons for Removal of Pb(II) Ions from Aqueous Solution
Abstract Introduction: The Lead causes severe damage to several systems of the body, especially to bony tissues. Until now, several low-cost biosorbents have been studied for removal of heavy metal ions from aqueous solutions. In the present study, carbonized pomegranate peels modified with Fe2+ and Fe3+ ions and then it was investigated for removal of Pb(II) ions from aqueous solution. ...
متن کاملSpontaneous unilamellar polymer vesicles in aqueous solution.
A unilamellar polymeric vesicle is a self-assembled structure of a block copolymer that forms a spherical single bilayer structure with a hydrophobic interlayer and a hydrophilic surface. Due to their enhanced colloidal stability and mechanical property, controllable surface functionality, or tunable membrane thickness, polymeric vesicles are useful in nano and bio-science, providing potential ...
