Application

• Smartphone-based COD analysis: A decentralized approach utilizing smartphone-based methods for on-site chemical oxygen demand (COD) and color analysis has been developed, enhancing the flexibility and accessibility of environmental monitoring in various applications, including pharmaceutical water quality testing (Cardozo et al., 2023).


• Wastewater treatment optimization: Research has applied COD calibration standards in the assessment and modeling of effluent quality and economic benefits from brewery wastewater treatment, integrating advanced computational tools to maximize efficiency and reduce environmental impacts (He et al., 2023).


• Runoff water quality analysis: Studies have utilized COD calibration standards to analyze the quality of stormwater-induced runoff influenced by land use patterns, providing crucial data for environmental management and regulatory compliance in the biotech industry (Pal et al., 2023).


• Cardiovascular data categorization: Although indirectly related, the use of accurate data calibration standards, similar to those used for COD, supports the development and validation of models categorizing cardiovascular causes of death, underlying the importance of standardization in biomedical research (Patel et al., 2022).
