TL;DR: A photometric phenylfluorone method for the determination of traces of tantalum has been developed in this article, where the interference of other metals is eliminated by virtually isolating the tantalum by solvent extraction from hydrofluoric- hydrochloric acid solution with methyl isobutyl ketone and by masking with (ethylenedinitrilo) tetraacetic acid during the subsequent color development.

TL;DR: In this paper, the influence of the ratio of phase volumes, temperature, and rotational speed on phenol removal was investigated using methyl isobutyl ketone as an extracting solvent.
Abstract: The aim of this work is the study of batch liquid-liquid extraction of phenol from aqueous solutions in a bench-scale well-mixed reactor. The influence of the ratio of phase volumes, temperature, and rotational speed on phenol removal (0.72–1.1 % w/w) was investigated using methyl isobutyl ketone as an extracting solvent. For this purpose, the ratio of phase volumes were set at 0.1 and 0.2, the temperature at 10, 20, and 30 °C, and the rotational speed at 300, 400, and 500 rpm. A physical model based on the material balance of the phases as well as the equation of mass flux between the phases allowed the estimation of the overall coefficient of mass transfer coupled with the superficial area. Moreover, it proved to fit, satisfactorily well, the experimental data of residual phenol concentration in the organic phase versus time under all the conditions investigated.

TL;DR: In this article, a flame-ionization detector was used for the analysis of volatile polar organics such as acetone, methyl ethyl ketone and tretrahydrofuran.
Abstract: Procedures for the quantitative analysis of industrial effluents which involve concentration by solvent extraction or the purge-and-trap method are time-consuming, labor-intensive, and prone to error. Direct aqueous injection gas chromatography using an electron-capture detector for the analysis of volatile halocarbons at the ppb level is in routine use in many laboratories. We now discuss the development of a similar protocol for the analysis of volatile polar organics such as acetone, methyl ethyl ketone, methyl isobutyl ketone, and tretrahydrofuran using a flame-ionization detector.
