dc.description.abstract | In this study, a rapid and simple ultraviolet‐spectrophotometric method was developed and validated for the quantitative determination of esterquat‐containing flotation collector FLOT 2015 in aqueous solutions. This method is based on the formation of an ion pair by FLOT 2015 and bromocresol purple, an anionic dye, and the subsequent measurement of the reduction in absorbance without extraction by organic solvents. The optimum conditions for FLOT 2015 detection and analysis were established. Sample solutions were stable up to 3 h. Maximum absorbance was obtained at 574 nm. The proposed method showed linearity in the range of 5–45 μg mL−1 with a correlation coefficient of 0.9917. Standard and relative standard deviation obtained by intraday and interday precision tests of the proposed method were within the permissible bias range and considered satisfactory. This method was found to be selective and specific for successful determination of FLOT 2015 in aqueous flotation systems. | nb_NO |
