    Notes: Everbearer strawberries containing carbofuran residues were subjected to chemical and physical aqueous washes to determine the removal of the chemical residues. The washed berries were processed into jam and a taste panel evaluated the effects of the treatments on the appearance, flavor and odor of the jam. The loss of total residues as determined by gas chromatographic analyses ranged from 63.1% on unwashed berries to as much as 100.0% on specifically processed samples. The chemical and physical treatments did not adversely affect the appearance, odor or flavor of the strawberry jam.

    Separations via continuous parametric pumping (1972)

    Notes: A continuous pump in which the feed and product streams flow steadily both in upflow and downflow is experimentally investigated in the model system toluene-n-heptane on silica gel adsorbent. The experimental data compare reasonably well with analytical results based on an equilibrium theory. The operating conditions necessary to achieve high separation factors are shown to be dependent on the relative magnitudes of penetration distances and the height of the column.

    Separations via semicontinuous parametric pumping (1973)

    Notes: A semicontinuous parametric pump with batch operation during one half-cycle and continuous operation in the other half-cycle was experimentally investigated using the model system toluene-n-heptane on silica gel adsorbent. A mathematical model based on an equilibrium theory is presented and is found to be in good agreement with the experimental results. Furthermore, it is shown that when the penetration distance for the cold cycle is less than or equal to that of the hot cycle and the height of the column, the rate of production of pure solvent by this pump may become quite large compared to the rate of production by a pump in which operation is continuous during both half-cycles.

    Separation of multicomponent mixtures via thermal parametric pumping (1974)

    Notes: A thermal continuous parametric pump for separating multicomponent mixtures was experimentally investigated using the model system tolueneaniline-n-heptane on silica gel adsorbent. A simple method for predicting separations is presented and is found to be in good agreement with the experimental results. The method, based on an equilibrium theory, invokes the assumption that a multicomponent mixture contains a series of pseudo binary systems. Each binary system consists of one of the solutes as one component and the common inert solvent as the other component.
