Large-scale Enrichment of Sulfur-containing Acid in Acetonitrile Using Triazine Analog as the Derivatizing Reagent for Desorption from Humic-fraction-modified Silica Gel
Autor: Shun-Wei Hu, Shushi Chen
Publikováno v: Journal of the Chinese Chemical Society. 63:703-708
The analog of triazine is used as the derivatizing reagent for enriching large-scale acid (e.g. amino acid) containing a sulfur atom on the humic-fraction-modified silica gel in acetonitrile and desorbing from the adsorbent in hexane, respectively. T

Autor: Shushi Chen, Yu-Xuan Gao
Publikováno v: International Journal of Molecular Sciences
Volume 19
Issue 10
International Journal of Molecular Sciences, Vol 19, Iss 10, p 2851 (2018)
In this study, the adsorption of lignin-modified silica gel after association with six different organophenylmercuric compounds in chloroform was investigated. Adsorption reached approximately 90% of the maximum value within 15 min. The adsorption ca

A Multipurpose Lignin-based Adsorbent for Metallic Ions, Nanoparticles and Various Organophosphate Pesticides in Hexane
Autor: Shun-Wei Hu, Shushi Chen
Publikováno v: Journal of the Chinese Chemical Society. 62:875-888
A lignin-based adsorbent for metallic ions, nanoparticles and various agricultural organophosphate pesticides in hexane is immobilized on silica gel without further fractional purification. For most organophosphate analytes examined in this study und
