The efficiency of cationic-based hydrogels in heavy metal removal from wastewater

Bakıt BORKOYEV | Kalıypa SALİYEVA

The present study draws attention to arsenic (V) (As(V)), chromium (III) (Cr(III)), and chromium (VI) (Cr(VI)) heavy metal pollutants, which have negative effects on aquatic ecosystems and indirectly pose a serious threat to the health of living things in the environment. Homopolymer and copolymer hydrogels were synthesized by the UV polymerization technique using 2-acrylamido-2-methyl-1-propansulfonic acid sodium salt (AMPS) and 3-acrlylamidopropil-trimethyl ammonium chloride monomers, and a crosslinker aimed to improve the swelling properties and metal sorption of the prepared hydrogels.

Superabsorbent hydrogels based on N,N-dimethylacrylamide and maleic acid for applications in agriculture as water purifier and nitrogen carrier

Nahit AKTAŞ

To reduce water pollution caused by fertilizers in agricultural irrigation, highly swelling crosslinked hydrogels (p(DMAAm-co-MA) or DM1) based on N,N-dimethylacrylamide (DMAAm) and maleic acid (MA) were prepared using a chemical initiator with the redox polymerization technique. Negative and positive surface modifications of DM1 were achieved using hydrochloric acid (HCl) (p(DMAAm-co-MA)/HCl or DM2) and sodium hydroxide (NaOH) (p(DMAAm-co-MA)/NaOH or DM3), respectively. The synthesized hydrogels were named DM1, DM2 and DM3, respectively. The swelling properties, urea sorption and urea release ...Daha fazlası
