▎ 摘　　要

NOVELTY - A tryptophan ionic liquid loaded magnetic graphene oxide nanocomposite is prepared by loading a tryptophan ionic liquid by ultrasonic vibration on a surface of iron(II,III) oxide dope silicon dioxide dope graphene oxide magnetic nanoparticles to obtain the finished product of iron(II,III) oxide dope silicon dioxide dope graphene oxide dope (1-n-butyl-3-methylimidazolium salt)tryptamine. USE - Tryptophan ionic liquid loaded magnetic graphene oxide nanocomposite for detecting tebuconazole extraction (claimed). ADVANTAGE - The tryptophan ionic liquid loaded magnetic graphene oxide nanocomposite has successfully measured water, rice, corn and soil sample. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is also included for a method for detecting a tebuconazole extraction.
