Abstract In this study, we report the synthesis of arsenic-imprinted polymer (As-IIP) through the combined effect of dual functional monomers, 4-vinyl pyridine, and methacrylic acid based ionic interaction by a simple and cost-effective ultrasonic-mediated precipitation polymerization. Ultrasonic energy application reduces the reaction time as compared to conventional protocol. Surface morphology and functionality were examined using SEM and FT-IR. Adsorption mechanism and kinetics was describes by Langmuir, followed by pseudo second order. The repeatability and selectivity of As-IIP were also evaluated. The As-IIP revealed excellent selectivity toward As3+ in the presence of Al3+, Cr3+, Hg2+, and Ni2+ high anti-interference ability in the presence of various coexisting ions. An excellent linear range of concentration (2–100) μg L−1 as well as LOD and LOQ were obtained 0.65 and 1.8 μgL−1 respectively. The synthesized As-IIP was applied for selective removal of toxic As3+ ions in real samples. Keywords Dual monomer . Methacrylic acid . 4-vinyl pyridine . Ionic interaction . Polymerization . Arsenic
Introduction Arsenic pollution in the environment can cause severe effects due to its high toxicity, worldwide circulation in soil, water, air, and lastly became a part of our food. The remediation and monitoring of arsenic pollution are becoming a research hotspot and received worldwide concerns [1–6]. Arsenic is mobilized into natural waters both by natural as well as anthropogenic sources that as biological Activity, volcanic emissions, geochemical reaction

and other anthropogenic activities, Mining activities, the use of arsenic pesticides, combustion of fossil fuels, herbicides, and arsenic additives [7–9]. Due to the high toxicological effect, the WHO and U.S Environmental Protection Agency have revised the maximum contaminate level (MCL) of arsenic from 50 ppb to 10 ppb in drinking water [10–12]. In nature, arsenic exists in both inorganic and organic forms. Inorganic species, i.e. arsenate, and arsenite are more lethal than organics for
