This communication presents results pertaining to the adsorptive studies carried out on fluoride removal onto an algal biosorbent (Ulva fasciata). Batch sorption studies were performed and the results revealed that biosorbent demonstrated ability to adsorb the fluoride. Influence of varying conditions for removal of fluoride such as the fluoride concentration, the dosage of adsorbent, the size of adsorbent, and the concentration of metal solution was investigated. Experimental data showed good fit with the Langmuir's adsorption isotherm model. Maximum fluoride sorption was observed at 30°C operating temperature.Keywords

Ultrasonic velocity, viscosity and density of ethyl oleate in butanol have been determined at various temperatures in the range 303.15-318.15 K. These data are used to estimate adiabatic compressibility, intermolecular free length and acoustic impedance, molar volume and free volume along with their excess values. The observed variations in these parameters with different concentrations and temperatures are discussed in terms of the intermolecular interactions between the unlike molecules of the binary mixtures.Keywords
