A critical approach to the fundamentals and use of a wide range of instrumental analytical techniques. Their application in problem-solving, with emphasis on environmental systems. Speciation analysis and modelling. Analysis of trace organics and atmospheric components. Metals in aquatic systems: complexation, absorption and redox processes.
The course content is divided equally between ‘analytical chemistry’ and ‘environmental chemistry’, but the two parts are strongly integrated.Environmental chemistry is the study of chemistry in the biosphere: the fundamental chemical processes and the impact of humans on these. The course will discuss the significant properties of aquatic systems, with particular reference to trace elements and compounds and the analytical methods for their determination.Analytical chemistry is the science of measurements in chemical systems. It is problem- driven, with applications typically in ‘real systems’ with complex matrices (e.g. sea water). Analytical chemistry involves an understanding of instrumental techniques: the theory, advantages and limitations, and the quality of the information obtained. It involves consideration of reliability (detection limits, precision), selectivity and sensitivity, validation, method optimisation, improving instrumental capabilities, and correct application of standards. In this course a wide range of applications will be addressed, but the emphasis will be on environmental systems.The course is generic, embracing aspects of organic, inorganic and physical chemistry. Lectures cover a range of methods for trace analysis. Specific topics covered in the course are:• Techniques for environmental analysis, sample pre-concentration and speciation;• Spectroscopic techniques: ICP-MS, ETAAS, HGAAS;• aquatic systems: colloids, complexes and redox processes;• speciation modelling and measurement;• electroanalytical techniques;• trace organic analysis in which two or more analytical instruments are coupled;• water quality monitoring and quality assurance.

LABORATORIES - This course has no component of laboratory work.However, because laboratory work is extremely important in environmental and analytical chemistry, it is highly recommended that students also take an appropriate laboratory course in conjunction with this course. The best course to take is CHEM382 (“Instrumental Methods”).
