Stepwise pH-gradient elution for the preparative separation of natural anthraquinones by multiple liquid-liquid partition.
Preparative-scale separation of substituted anthraquinones by multiple liquid-liquid partition was studied using isopropylmethyl ketone (IMK)/aqueous phosphate buffer (aq.) as the solvent system and the Hietala apparatus with 100 partition units as the partition equipment. The lower (aq.) phase was chosen as mobile, while the upper (IMK) phase remained stationary. Hence, the principle of stepwi...
متن کاملPreconcentration of acrylamide with dispersive liquid-liquid microextraction based on solidification of floating organic drop prior to determination by HPLC
A novel, rapid, simple and sensitive dispersive liquid-liquid microextraction method based on the solidification of floating organic drop (DLLME-SFO) combined with high performance liquid chromatography-ultra violet detection (HPLC-UV) was used to determine acrylamide in potato chips. The derivation of the acrylamide happened in the presence of KBr, KBrO3, H2SO4. Based on studies, 1-undecanol w...

متن کاملOff-line Coupling of Ionic Liquid-Based Dispersive Liquid-Liquid Microextraction to HPLC-UV Method for the Drug Analysis in Pharmaceutical and Biological Samples
In this study, an easy, fast, sensitive and accurate technique has been described for extraction and quantitative analysis of fluoxetine and propafenone using off-line coupling of ionic liquid–based dispersive liquid–liquid micro-extraction with high performance liquid chromatography. The effective extraction variables including: the ionic liquid volume, the type and volume of dispersive solven...
متن کاملOptimized preconcentration of Imatinib using dispersive liquid-liquid microextraction coupled with HPLC-UV
Background: Imatinib is an antineoplastic agent acting as a tyrosine kinase inhibitor to treat cancer such as lymphoblastic leukemia. The dosage of the anticancer drugs plays a critical role in the survival of the patients. For this reason, the patient's plasma and urine samples should be monitored to obtain the necessary information regarding the toxicity of the drug. In this study, the applic...
