“…Penentuan kandungan SDBS dapat dilakukan dengan beberapa metode seperti spektrofotometri UV-Vis, titrimetric [8] , High Performance Liquid Chromatography (HPLC) dan elektroforesis kapiler. Kelebihan analisis surfaktan menggunakan metode HPLC dan elektroforesis kapiler memiliki akurasi dan kepekaan yang tinggi tetapi memerlukan biaya yang mahal [14] . Metode titrimetri memiliki akurasi dan kepekaan yang rendah [16] .…”

Method validation of sodium dodecylbenzene sulfonate (SDBS) analysis in catfish by maceration and UV-Vis spectrophotometry using methylene blue active substances (MBAS) method was performed. The first stage of this research was method validation comprising correlation coefficient, sensitivity, Limit of Detection (LOD), Limit of Quantitation (LOQ), precision, and accuracy. The extraction of SDBS by maceration with methanol for 16 h and analysis by UV-Vis spectrophotometry using MBAS were performed. Then, this method was applied to analyze SDBS in catfish. The results of validation of SDBS analysis in cultivated catfish give correlation coefficient 0.9944, sensitivity 10.57 × 104 L mol-1 cm-1, LOD 0.01776 mg/L, LOQ 0.05922 mg/L, precision 0.1351-1.300 %, and accuracy 87.64-90.01 %, respectively. The SDBS concentrations in fish increase with the increase in the SDBS concentration in cultivating water. Bioconcentration Factor (BCF) values were inversely proportional to the concentration of SDBS in the cultivating water. The concentrations of SDBS on catfish, tilapia, and carp in traditional markets were 5.719-8.162; 5.180-6.548; and 2.973-5.874 mg/kg, respectively. In general, analysis method of SDBS in catfish by maceration and UV-Vis spectrophotometry with MBAS show a good result and can be used as a routine analysis in fish.

Perfluoroalkyl substances are chemical pollutants whose levels in the environment should be monitored. This work implemented nonaqueous capillary electrophoresis with conductivity detection to achieve separation of perfluoroheptanoic acid, perfluorooctanoic acid, and perfluorooctanesulfonate within 5 min. The mixture of 3‐(N‐morpholino)propanesulfonic acid and triethylamine in acetonitrile/methanol (50:50, v/v) was used as a background electrolyte. The method was linear (coefficients of determination ˃ 0.996) at analyte concentrations ranging from 2 to 20 μM with instrument detection limits varying between 0.30 and 0.75 μM depending on the analyte. The developed method was precise, the relative standard deviation of repeatability (n = 6) and reproducibility (n = 5) were less than 5.8% for the analytes used. The method was applied to the analysis of perfluoroheptanoic acid, perfluorooctanoic acid, and perfluorooctanesulfonate in wastewater samples treated by solid‐phase extraction, which further made it possible to achieve the method detection limits of perfluoroalkyl substances as low as 0.1–0.4 nM. Additionally, the applicability of the novel carbon aerogel‐based solid‐phase extraction and magnetic solid‐phase extraction were tested for the extraction of target compounds. It would be possible to transform the developed method into a portable format for on‐site analysis.
