摘要

采用超声辅助微通道萃取(UAME)法，用二(2-乙基己基)磷酸(D2EHPA)从湿法磷酸中提取铁(III)。系统研究了超声功率、萃取剂浓度、水相速度和有机水相比(O/A)对Fe(III)提取率的影响。结果表明，Fe(III)的提取效率达到91.08%，显著高于超声提取和微通道提取。采用响应面法确定最佳提取条件，并对影响提取效率的变量进行显著性评价。在萃取剂浓度为2.1 mol/L的条件下，Fe(III)的萃取率可达92.24%;水相流速0.055 mL/min;有机相与水相之比为2.98。

Ultrasonic Assisted Microchannel Extraction of Fe(III) from Wet-Process Phosphoric Acid

An ultrasonic assisted microchannel extraction (UAME) method was developed for the extraction of Fe(III) from wet-process phosphoric acid with di(2-ethylhexyl)phosphoric acid (D2EHPA). The influences of ultrasonic power, extractant concentration, water phase velocity and the ratio of the organic and aqueous phases (O/A) on the extraction rate of Fe(III) were systematically studied. The results showed that the extraction efficiency of Fe(III) reached 91.08%, which was significantly higher than that for ultrasound extraction and microchannel extraction respectively. Response surface methodology was adopted to obtain the optimal conditions and to evaluate the significance of variables affecting the extraction efficiency. The extraction efficiency of Fe(III) reached 92.24% under the following optimum conditions: extractant concentration, 2.1 mol/L; aqueous phase velocity, 0.055 mL/min; ratio of organic phase and aqueous phase, 2.98.

期刊介绍： Solvent Extraction Research and Development, Japan (Solvent Extr. Res. Dev., Jpn.) is a periodical issued from Japan Association of Solvent Extraction (JASE) containing papers dealing with all aspects of solvent extraction and their related methods, underlying principles, and materials. Original articles, notes, technical reports, and critical reviews will be considered for publication. Original articles must be of reasonably broad scope and significance to the solvent extraction. Notes will originally describe novel work of a limited nature or especially significant work in progress. Authors can contribute some information of novel techniques, equipment or apparatus, reagents and diluents for solvent extraction as technical reports. Critical reviews will be received from the authors to whom the editorial committee asked to contribute.
