Raw FA was firstly modified by ball milling (FA-I) followed by the NaOH hydrothermal (130 °C) and H2SO4 etching processes (FA-II). Quaternary ammonium groups were then introduced by either physically covering the ash with cationic surfactants CTAB (FA-CSC) or silane coupling methods with TTPAC (FA-SCA). Various dosage of TTPAC were evaluated such as 30 wt% and 100 wt% of the modified FA (denoted as FA-SCA30 and FA-SCA100, respectively). Details of modification methods were included in SI section 1.
Surface morphology was characterized using a scanning electron microscope (SEM, ZEISS GeminiSEM 500). The introduced quaternary ammonium was validated using an attenuated total reflectance-Fourier transform infrared spectroscopy (ATR-FTIR, PerkinElmer). The Brunauer–Emmett–Teller surface area (SBET) and pore volume (Vpore) were analyzed by a BET analyzer (MicrotracBEL, Belsorp max). The size distribution (via dynamic light scattering, DLS) and zeta potential were carried out using a Zetasizer (Malvern, Nano ZSE) with the refractive index of 1.45. The percentile values (D10, D50 and D90) were measured to indicate the cumulative 10%, 50% and 90% point of diameter in volume distribution, respectively. The volume mean diameter, as well as the span ((D90-D10)/D50), were calculated for a better description of particle size and distribution.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
