Application
- LC-HRMS methods for the quantification of two artemisinin drugs and their metabolites in rat blood and plasma.: This study develops a liquid chromatography-high resolution mass spectrometry (LC-HRMS) method using potassium dichromate as a calibration standard, significantly enhancing the accuracy and precision in pharmaceutical analysis (Zhou et al., 2024).
- A novel model extended from the Bouguer-Lambert-Beer law can describe the non-linear absorbance of potassium dichromate solutions and microalgae suspensions.: Research presents a novel mathematical model incorporating potassium dichromate, offering a more accurate method for assessing the optical properties of solutions, critical for analytical applications in bioengineering and environmental studies (Yeh et al., 2023).
- Melatonin Alleviated Potassium Dichromate-Induced Oxidative Stress and Reprotoxicity in Male Rats.: Investigates the protective effects of melatonin against oxidative stress caused by potassium dichromate in clinical settings, providing insights into its potential therapeutic applications (Bashandy et al., 2021).
- Assessing the acute and chronic toxicity of exposure to naturally occurring oil sands deposits to aquatic organisms using Daphnia magna.: Features a study on the environmental impact of potassium dichromate, providing essential data for environmental toxicology and pollution assessment (Cardoso et al., 2020).
