Inactive Diamex Test with the Optimized Extraction Agent Dmdohema
نویسنده
چکیده
In the frame of the development of the DIAMEX process, first studies including counter-current hot tests were performed, with the DiMethyl-DiButylTetraDecylMAlonamide as reference extractant. In parallel, the diamide formula has been optimised so that a new extractant was proposed: the DiMethylDiOctylHexylEthoxyMAlonamide. This new reference extractant was used in two inactive flowsheets. The performances obtained were satisfying and confirmed the choice of DMDOHEMA as the new reference extractant for the DIAMEX process

Optimized 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...
متن کاملTowards a Diamex Process Flowsheet Using High Active Concentrate ( Hac
The efficiency of MA recovery in the DIAMEX process has already been demonstrated using HAR. The next step aims at the demonstration of reprocessing from HAC as feed, in view of an industrial application. The volume reduction would reduce the size of the installation and thereby the costs of the process. The first step towards the demonstration of a DIAMEX process using HAC is the production of...
متن کاملSelective Cloud Point Extraction and Preconcentration of Copper by the Use of Dithizone as a Complexing Agent
The aim of this work was to develop a selective cloud point extraction method for the separation and preconcentration of copper(II) prior to spectrophotometric determination. For this purpose dithizone was used as a complexing agent and the experimental solution was acidified with sulfuric acid. Triton X-114 was used as a surfactant and after phase separation, based on the cloud point of th...
متن کاملSanex - Btp Process Development Studies
Bis-triazinyl-pyridines (BTPs) have been developed at CEA-Marcoule to separate actinides(III) from lanthanides(III). Although high separation performances were observed in the counter-current hot test carried out in 1999 on a highly active effluent, the extraction and back-extraction yields of actinides(III) were lower than expected from calculation. A strong sensitivity of the extractant towar...

Dispersive liquid–liquid microextraction (DLLME) combined with inductively coupled plasma-atomic emission spectrometry (ICP-AES) was applied for the determination of lead in different environmental water samples. Ammonium pyrrolidine dithiocarbamate (APDC), chloroform and ethanol were used as chelating agent, extraction solvent and disperser solvent, respectively. The effective parameters, such...
