▎ 摘 要
NOVELTY - Use of a graphene oxide composite material as a matrix solid phase dispersant, is claimed, where the material comprises graphene oxide and Florisil (RTM: Hard powdered magnesia-silica gel). USE - Graphene oxide composite material for use as a matrix solid phase dispersant for detecting eighteen types of mycotoxins in wheat flour samples. ADVANTAGE - The material can improve detection rate of mycotoxin, and provide better versatility, sensitivity and detection limit that meets the standard requirements.
