A simple, low-cost, and accurate method was developed to quantify and optimize BTEXS in water. The results showed that using GC-FID analysis method is effective in measuring BTEXS. Additionally, the use of Co-MCM-41 nanocatalyst can efficiently remove BTEXS from water.
BTEXS, a group of aromatic hydrocarbon pollutants, is widespread and hazardous. Using headspace and gas chromatography (GC) coupled to a flame ionization detector (FID) as a newly developed simple, low-cost, and accurate method is used to determine and optimize the quantifying BTEXS in water using the Taguchi method. As part of the validation process, linearity, detection limits, and accuracy were investigated. The LOD and LOQ ranged between 0.03-0.32 mg/L and 0.1-1.09 mg/L, respectively. Statistically, the relative standard deviation was less than 12.69% (n = 21). At mg/L levels, headspace coupled to GC-FID is an effective BTEXS analysis method. The Co-MCM-41 nanocatalyst was successfully used to remove BTEXS at levels of 79.27% and 78.61%, respectively, in laboratory-spiked and industrial wastewater samples. The recuperation results appear to have incredible performance and application potential for the BTEXS sorbent. Reusability tests for Co-MCM-41 nanocatalysts showed the highest activity in nine consecutive reaction cycles.
