应用


  • Determination of 13 potential anti-obesity agents in hair by dispersive liquid-liquid microextraction-assisted UHPLC-MS/MS.: This study employs sodium dodecyl sulfate in a novel extraction technique for quantifying anti-obesity agents, showcasing its pivotal role in enhancing the sensitivity and accuracy of bioanalytical methods (Tang et al., 2024).

  • Sequestration of cyanide ions from aqueous medium by physio-chemically fabricated biochar of peels of banana and grape fruit in ecofriendly way.: Demonstrates the use of sodium dodecyl sulfate in enhancing the adsorption capacity of biochars, which is vital for environmental remediation technologies (Sillanpaa et al., 2024).
