“…The efficiency of PHAs removal by the cotton and wool fibers reached 71.0% (with absorption of up to 71.0 µg cig−1) and 60.5% (with absorption of up to 60.5 µg cig−1), respectively. Compared with the Zhongnanhai filter tip used in this study (54.0%), the filtration efficiency of the cotton and wool fibers was increased by 17.0% and 6.5%, respectively.…”
