Synthesis of a novel crosslinked superabsorbent copolymer with diazacyclooctadecane crown ether and its sorption capability

Removal of heavy metals by homolytically functionalized poly(acrylic acid) with hydroquinone

“…The adsorption capacity of the adsorbent is more for lead when compared to other metals, because the stability constants of complexes of lead with carboxylates and phenols are greater than those for other metals [33,34]. The cross-linked poly(acrylic acid-co-Kryptofix-22-DM) [36], the tetrahydroxybenzenefunctionalized PAA [5], and the tetrahydroxybenzenefunctionalized PAAm [14] showed the same order of sorption capacity. Overall, our results are within with those reported in the literature (Table 7).…”

Synthesis of clay-based superabsorbent composite and its sorption capability

“…Because of their superior properties they have hygienic, agricultural, medical and pharmaceutical applications [2,3]. In such applications, water absorbency and water retention are essential [4].…”

“…In such applications, water absorbency and water retention are essential [4]. Some authors modified these absorbent polymers to enhance their absorbency, gel strength, and absorption rate [1][2][3][4]. In recent years, the preparation of organic-inorganic superabsorbent composites has attracted great attention because of their relatively low production cost, high water absorbency and their considerable range of applications in agriculture and horticulture [1,4].…”

Synthesis and swelling behavior of poly (acrylic acid-acryl amide-2-acrylamido-2-methyl-propansulfonic acid) superabsorbent copolymer

“…As is well known, salt-resistance ability is very important to SAPs and it depends on functional group, crosslinking density and reaction conditions (Chen et al 2005;Murthy et al 2006;Mohan et al 2005;Lee and Huang 2007;Yılmaz and Kul 2007;Xu et al 2007; Vandamme and Lenourry 2002;Karadaǧ and Saraydin 2002;Wu and Lin 2000;Pourjavadi et al 2007;Li et al 2007). In this study, with the purpose of improving the salt-resistance ability, a new SAP has been synthesized in aqueous solution using acrylic acid (AA), acryl amide (AM) and 2-acrylmido-2-methylpropanesulfonic acid (AMPS) as monomers.…”
