“…Moreover, they can possess various surface functional groups with an affinity for different adsorbates, so these features provide them with high adsorption kinetics and capacities [ 19 ]. Previous studies have proved the ability of ACF to remove numerous pollutants contained in water, namely pesticides [ 20 ], metal ions [ 21 ], and organic micropollutants [ 22 ]. Moreover, the adsorption capacity of pesticides by ACF were found to be significantly higher than that of granular activated carbon due to a smaller diameter of fibers, which leads to a larger surface area accessible to pesticides, as well as narrower micropore size distribution, which enables a lower mass transfer resistance [ 23 , 24 ].…”

Extensive use of pesticides resulting in their accumulation in the environment presents a hazard for their non-target species, including humans. Hence, efficient remediation strategies are needed, and, in this sense, adsorption is seen as the most straightforward approach. We have studied activated carbon fibers (ACFs) derived from viscose fibers impregnated with diammonium hydrogen phosphate (DAHP). By changing the amount of DAHP in the impregnation step, the chemical composition and textural properties of ACFs are effectively tuned, affecting their performance for dimethoate removal from water. The prepared ACFs effectively reduced the toxicity of treated water samples, both deionized water solutions and spiked tap water samples, under batch conditions and in dynamic filtration experiments. Using the results of physicochemical characterization and dimethoate adsorption measurements, multiple linear regression models were made to reliably predict performance towards dimethoate removal from water. These models can be used to quickly screen among larger sets of possible adsorbents and guide the development of novel, highly efficient adsorbents for dimethoate removal from water.

“…Also, they can possess various surface functional groups with an affinity for different adsorbates, so these features provide them high adsorption kinetics and capacities (Hassan et al, 2020). Previous studies have proved the ability of ACF to remove numerous pollutants contained in water, namely pesticides (Faur et al, 2005), metal ions (Berber-Mendoza et al, 2018), and organic micropollutants (Zhao et al, 2020). Moreover, studies have shown that the adsorption capacity of pesticides by ACF is significantly higher than that of granular activated carbon due to a smaller diameter of fibers which leads to a larger surface area accessible to pesticides as well as narrower micropore size distribution which enables a smaller mass transfer resistance (Cougnaud et al, 2005;Martin-Gullon and Font, 2001).…”

“…In addition, these adsorbents are mostly used to remove heavy metals. 20,21 Few studies have been reported on the recovery of indium from aqueous solutions using modified ACF. Chemical grafting modification involves grafting molecules onto the ACF surface through chemical reactions.…”
