different classes of alcohols generated in this work, it is now possible to predict reverse osmosis separations of many alcohol solutes from data on membrane specifications given in terms of A and Dam/K6 for NaCl only. This predictability is illustrated in this paper for the Ci to Cg alcohols using cellulose acetate membranes of different surface porosities. This prediction technique can be extended to a wide variety of organic solutes in aqueous solutions where reverse osmosis separations are governed by polar, steric, and/or nonpolar effects and preferential sorption of water at the membrane-solution interface. This possibility opens new areas of reverse osmosis investigations involving a wide variety of organic solutes many of which are of practical interest from the point of view of water pollution control.Literature Cited

We have calculated the project range for ions on amorphous targets made of ternary or quarternary alloys. Our calculations are based upon Vagard's law, which establishes that the project range in multi-component system can be obtained by linear combination of those of its composing binary alloy compounds. The calculated project ranges of systems, H+→GaAlAs, InAs and InGaAs, Be+→ GalnSb and InAsSb, and B+ →Cd0.2Hg0.8Te, agree well with the experimental or calculated results published in literatures. The dependences of project range on implanting energy and composition in the processes H+→ GaInAsP and GaAlAsSb, and ions→ PbSnTe are also calculated.
