SIMPLIFIED QUALITY CONTROL METHOD APPLICABLE TO COPPER (1) OXIDE BASED ANTIFOULING PAINTS

To reduce the time and expense involved in leaching studies, a simple technique has been developed to continuously monitor the increase in copper concentration during the leaching of antifouling paints in alkaline glycinate accelerated leaching solutions. The copper concentration is measured by direct estimation of the copper glycine complex using a simple immersion absorptiometer. This paper briefly describes the techniques and apparatus used. The absorptiometer head, which consists of an incandescent light source and vacuum photodetector, is treated in more detail. The use of the technique is illustrated by experimentally-determined leaching curves of contact leaching antifouling paints, indicating the effect of changes in pigment volume content, vehicle type, and pigment trade. This method and apparatus developed for routine quality assessment appears capable of refinement to yield more detailed information for use in research and development.
