Herein, we present a simple and feasible one-step method to prepare amine-rich Accepted 23 March 2019 porous polyamidoamine (PAMAM) dendrimer gel adsorbent. The PAMAM gel could be readily separated Available online 25 March 2019 from water by ﬁltration. The adsorption properties of PAMAM gel was systematically examined by adsorption of anionic methyl orange (MO) and tartrazine (TTZ) dyes. The PAMAM gel exhibited superior Keywords: adsorption selectivity and removal efﬁciency towards anionic MO and
