文摘
- •
A chip-based GO/SiO2 MISPE monolithic column array coupled with HPLC was established.
- •
Rhodamine B existed in real sample which tested on chip-based array columns was enriched more than 110 times.
- •
The GO/SiO2 MISPE columns showed good ability of impurities removal and excellent selectivity.
- •
The prepared columns and chips can be reused for at least 30 times and extraction efficiency is almost the same.
- •
The method was proposed to analyze rhodamine B and LOD achieved 0.40 ng g−1.
