Abstract:
OBJECTIVETo remove plumbum ion from the extract of Lonicera japonica by gamma-mercaptopropyl-modified silica gel (MPS).
METHODThe reference plumbum ion solution was added into the extract of L. japonica as the tested samples. The static and dynamic adsorptions were investigated to evaluate the influent factors on the removal of plumbum ion in the extract. The solid content and HPLC profiles of the extract were determined to evaluate the process changes.
RESULTMPS showed excellent adsorption charateristics to remove plumbum ion from the extract of L. japonica, with fast adsorption rate and more than 80% removal efficiency. The optimum parameters were as follows: 6 times sample volume, 10 times of height to diameter, and 6 BV x h(-1) of flow velocity, at the temperature of 25 degrees C. During the removal process, obvious changes of solid content and HPLC profiles were not observed.
CONCLUSIONMPS could be used to remove plumbum ion from extract of L. japonica.
