CH2042 –Marine Chemistry and Chemical Ecology
(Taught every year, 1st Semester with A/Prof Bruce Bowden)
An introductory subject on the principles of marine chemistry and marine chemical ecology. Definition and history of marine chemistry and chemical ecology. Properties and chemical composition of seawater. Major elements in seawater. Conservative and non-conservative elements. Biogeochemical cycles. Horizontal and vertical distribution of bio-limiting elements. Determination of nutrients in seawater. Minor or trace elements in seawater, sediments and marine organisms. Bioaccumulation and biomagnification of trace elements in marine organisms. Trace element speciation and toxicity. Carbonate equilibria in the sea. Ecological role of dissolved organic carbon (DOC) compounds in seawater. Chemical communication conveyed by DOC, allochemical effects. Invertebrate-toxic host relationships, symbiosis and mutualism, coral spawning chemistry. Fatty acids, steroids, terpenes, nitrogenous compounds, fish and shellfish toxins. Potential applications of marine biotechnology-ectocrines and filter feeders, mollusk chemistry, tunichromes, metal ion sequestering and pharmacological activity.
JCU is the only University in Australia where we do chem pracs on Orpheus Island.
CH2103 – Analytical Chemistry
(Subject Coordinator, taught every year 2nd Semester, with Dr Mark Robertson)
Analytical Chemistry is branch of chemistry that provides qualitative information (what is in a sample) and quantitative information (how much is in a sample) about matter. A good knowledge of analytical chemistry is important in any discipline where the characterization of materials is important. The topics covered include: Core Skills in analytical chemistry -this topic spans data analysis and record keeping as well as classical volumetric, gravimetric and titrimetric techniques. Instrumental analysis in analytical chemistry- this topic covers a range of commonly encountered analytical techniques including AAS, ICP-AES, XRF, XRD (powder and single crystal),UV-Vis, Mass Spectrometry (including MALDI, ESI, CI and EI), Column Chromatography(including GC and HPLC) and combination (hyphenated techniques) including GC-HPLC, HPLC-MS, ICP-MS as well as modern electro-analytical methods including Potentiometric, Voltametric and Coulometric methods. Laboratory Management and safety- this topic covers commonly encountered methods of sample preparation, principles of Quality Assurance and Quality Control and appropriate documentation of analytical procedures and an introduction to Queensland Occupational Health and Safety (OH&S) legislation. All techniques and methods will be discussed in the context of a range of real, industrial, environmental, biological and medical contexts. As part of this course students will typically be given the opportunity to see some working analytical laboratories both on and off campus.
