In initial adsorption experiments appeared that C [4] BS was much more effective in adsorption of PNP rather than PHE, PCP and MNP, whereas DMC [4] BS exhibited too little adsorption ability towards all phenols. Herein, it was concluded that the hydrogen bonding capacities of both phenols and calix[4]arene based adsorbents played a predominant role in the interactions between adsorbate and adsorbent within the adsorption mechanism. Thus, in subsequent studies, the C [4] BS was employed as an adsorbent in the adsorption of PNP, and adsorption conditions were optimized. Furthermore, isotherm and kinetic studies were performed to clarify the phenomena of PNP adsorption onto C [4] BS.en10.1016/j.reactfunctpolym.2018.03.003info:eu-repo/semantics/closedAccessAdsorptionPhenolic compoundsHydrogen bondingp-NitrophenolCalixareneArticle1262735Q1WOS:000436214500004Q1
