The circular saw blade, which is mainly composed of carbon steel, is used to cut the stone. However, the carbon steel is easily corroded in stone processing wastewater, shortening its lifespan. In this study, a new composite inhibitor of sodium nitrite, sodium molybdate, sodium silicate, sodium tungstate, and sodium citrate was investigated firstly, and then, its inhibition efficiency for carbon steel in stone processing wastewater was explored using electrochemical measurements and weight loss measurements. The results showed that the composite inhibitor as a mixed-type inhibitor displayed go...
