Highlights New symmetric ILs were used for extraction of widely used toxic textile dyes from waste water;  Low amount of eco-friendly citrate salt was applied to generate ABS;  Efficiency of 99.4% for removal of Orange II in a single step extraction was achieved;  Maximal efficiency was obtained using minimal amounts of ABS ingredients;  Recycling procedure of applied ILs was successfully tested and proposed.

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 adsorption is seen as the most straightforward approach in this sense. 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 predict performance towards dimethoate removal from water reliably. 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.
