Response surface methodology-optimized mildly carboxylated cellulose for dispersive solid-phase extraction and trace determination of heavy metals in commercial beverages

Year: 2026

Type: article

Abstract: , average recoveries consistently fell within the 80-110% range. Notably, the method remained robust in fruit juice samples despite high organic content, maintaining stable recoveries for all target analytes and effectively mitigating matrix-induced interferences. These results underscore the stability of optimized functionalized cellulose as an eco-friendly and efficient d-SPE sorbent for routine trace metal monitoring in commercial food products.
