應用
- The para-chloroaniline prevention after the use of sodium thiosulfate as an intermediary irrigator between sodium hypochlorite and chlorhexidine.: This study evaluates the neutralization of sodium hypochlorite by sodium thiosulfate to prevent para-chloroaniline formation when combined with chlorhexidine. It provides insights into the optimal concentrations of sodium thiosulfate for safe and effective usage in analytical applications involving these chemicals (Endocrinology and Disorders, 2020).
