Achieving "Chromic Acid Zero" in Optical Glass Cleaning
"Chromic acid mixture," which has been used for many years in the cleaning of polished optical glass and quartz glass. However, due to the regulations on hexavalent chromium, waste treatment costs, and worker safety concerns, the introduction of alternative technologies has become an unavoidable issue. Therefore, we propose "electrolytic sulfuric acid cleaning," which achieves complete chromium-free status while possessing organic stain removal performance equivalent to that of chromic acid.
