✦ Synopsis


A modified XRF thin film analytical approach to the analysis of solution extracts from concretes has been developed and tested. Small volumes of solutions (lml) are evaporated on suitably machined copper discs. The thin film of evaporated salts produced is virtually free of absorption effects and provides a reproducible linear relationship between instrumental response and element concentration. thii copper disc evaporation test (CDET) is currently applied for analysis of Sulphate and chloride ions in solution.
