Field tests for determination of ion contamination on the surface before painting

摘要

Methods of determination of chlorides and sulfates contaminations on the surface of the construction were described The tests JONTEST Cl{sup}- IMP and JONTEST (SO{sub}4){sup}(2-) IMP for field use for measurement of concentration Cl{sup}- and (SO{sub}4){sup}(2-) ions in water solutions containing soluble contaminations were presented. Tests are easy to use, selective for the tested ions and exact for both high and low concentrations.
