Insights on extracting mechanisms and interference factors of solid-phase extraction for trace sulfamethoxazole enrichment
{{output}}
Sulfamethoxazole (SMX) has garnered global attention due to its presence in trace amounts (ng L-1 to μg L-1) in water bodies. Solid-phase extraction (SPE) is a key pretreatment step for analyzing trace SMX, and its efficiency significantly impacts the accurac... ...
