the purpose of this reaserch is to measure the phase equilibrium data of the ternary system (water + phosphoric acid + 1-nonanol) at different temperatures. experimental solubility curves and tie-line points for the system were obtained at t = 298.2, 308.2 and 318.2 k and ambient pressure. the binodal curve data were detected by the cloud point method. the mass fractions of each layer were achi...

We examined the relation between adolescent separation-individuation, family cohesion, and college adjustment. A large sample of college students was split into two groups. One group was used to determine whether several measures of separation-individuation were measuring different dimensions of individuation. Two related factors, labeled Positive Separation Feelings and Independence From Paren...

Separation of some biogenic amines via RP-HPLC using mixed micellar mobile phase was investigated. The compounds were derivatized before hand by dansyl chloride as a chromophoric reagent. Appropriate conditions for separation, were determined by studying factors such as temperature, type and percentage of organic modifier, concentration of surfactants (SDS and Brij-35) and the pH of the mobile ...

The novel nanocomposite membranes were successfully prepared by the incorporation of different concentrations (5, 10, and 15 wt%) of montmorillonite (MMT) as a nanoadditive into a blend of chitosan/polystyrene (CS/PS) at a ratio of 3:1 on the basis of solution-casting method and they were subsequently used for the separation of phenol, p-chlorophenol, and 2,4-dichlorophenol from water through p...

Five-zone Simulating Moving Bed (SMB) system, designed for ternary separation, is a modified form of standard four-zone SMB which is only effective in binary separation. It was reported in literature that the five-zone SMB separates the extract-II stream with a lower purity value than that of raffinate and extract-I streams. To address this issue, five zone SMB was designed, using safety ma...

Application of two-photon selective excitation to isotope separation with high power, high resolution tunable lasers is discussed. A simple kinetic model is given to determine quantum efficiency and separation factor in terms of laser powers and relaxation constants. A numerical example is used to demonstrate the feasibility of the scheme. Results indicate that a high quantum yield is obtainabl...
