“…4,5 Similar mechanism for the uptake of metal cations has been postulated for the metal phosphates. 6 While there is extensive literature now available and many more being published about the fixation of metal cations by oxides/hydroxides, phosphates and carbonates, very little information is present about the interaction of metal cations with sulphides.…”

The characterization and adsorption studies of Cd 2＋ on FeS were performed. Adsorption of Cd 2＋ from aqueous solutions on synthetic iron sulphide (FeS) was investigated as a function of pH (5-7) and temperature (303-323 K). It was found that the iron sulphide (FeS) had adsorptive properties comparable with those of other adsorbents reported in the literature. The sorption of Cd 2＋ was observed to increase with the increase in pH but not strongly sensitive to temperature. The adsorption data fitted both the Kurbatov and Langmuir adsorption models. In addition, ∆G values were calculated from the values of the binding constant, which showed that the cadmium adsorption process was spontaneous in nature.

“…The equations obtained from the linear regression analysis were was used to determine the thermodynamic parameters for each system, where the -is the slope and is the intercept (Table 9). which indicates inner-sphere adsorption due to the high amounts of energy required to form the strong covalent bonds (Krauskopf and Bird, 2003 adsorption to variable charge mineral surfaces (Mustafa et al, 2008;Mezenner and Bensmaili, 2008;Juang and Chung, 2004). Mustafa et al (2008) Because TΔS°a d is a large, positive value in all the systems and results in a negative ΔG°a d , the process is said to be entropically driven.…”

Many long hours of study and research have placed me at this point in my career, though I would be remiss if I failed to acknowledge those who helped guide and encourage my progress. First, I would like to acknowledge my Major Professor, Dr. Michael Essington, who has been both my friend and mentor. My gratitude must also be extended to my committee members, Dr. Mark Radosevich and Dr. Amy Johnson, for their support. Special thanks must go to Galina Melnichenko, without whose kindness and knowledge I would be lost. Thank you, Galina, for always being willing to help me work a problem through to a solution. I must also acknowledge my family and friends, whose love and encouragement has always been my shelter: my mother Virginia Jean Journey, who never lets me quit; my grandparents Thomas and Jean Journey; my grandmother Imma Lorene Bentley; my aunt Aurora Anne Daniels; and my best friends Amanda Odessa Beckner and Jennifer Lauren Webster, who have been like sisters to me. Finally, my thanks go out to all of those friends not mentioned who have never failed to show me love and support. I could never have come this far without you.
