reactions It IS a broad and mterestmg chapter, a useful source of information Modlfied electrodes are a popular topic with many (m my opmlon sometunes rather optnmstlc) prorntses This chapter IS big on theory and thm on successful apphcattons There appears to be a mlsunderstandmg m the use of the concentration terms pM and plcomole (which mdlcates a quantlty rather than a concentration) which makes a big dtierence when dlscussmg detectlon hmlts, furthermore different ~n~ntrat~on scales (ng and PM) are occasionally mured v&m one sentence This field 1s still developmg and there 1s undoubted potential for environmental apphcatlons mcludmg m vlvo (m&a-cellular) measurements The last chapter (Blosensors) is somewhat weaker, givmg statements sometimes unsupported by references Even so, many useful examples are given m this area which 1s still developing On the whole thts book prowdes a large amount of mformation, and the major part 1s well-written and mterestmg to read I recommend this book as a reference source for the title topic for researchers and analytIca chemists at postgraduate level C M G van den Berg

a computer spreadsheet (such as Lotus l-2-3, or Excel) Sample calculations are presented for many types of system Calculations mvolvmg the forma&on of complexes by metal Ions and hgands are included When copper ions are mtxed with hydroxide and ammoma, up to mne separate copper complexes may be mvolved, and the author shows how his systematic method deals with pH and speclatlon calculations for such systems Calculattons where one or more speczes preapttate out of solution are also discussed The methods presented are the result of many years of thought and quickly gwe answers for complicated mixtures This book 1s no easy read, but by persistence you can qmckly master these tricky calculations J R ChIpperfield
