Synthesis and Characterization of Novel Poly (Acrylic Acid/Sodium Alginate/Sodium Humate) Superabsorbent Hydrogels. Part II: The Effect of SH Variation on Cu{sup 2+}, Pb{sup 2+}, Fe{sup 2+} Metal Ions, MB, CV Dye Adsorption Study
- Harcourt Butler Technical University, Department of Plastic Technology (India)
A novel superabsorbent hydrogel (SAHs) composed of (acrylic acid, sodium alginate and sodium humate) (AAc/NaAlg/SH) SAHs were tested as adsorbent for metal ions Cu{sup 2+}, Pb{sup 2+}, and Fe{sup 2+} ions as well as MB and CV dyes. The influence of SH concentration varies from 6.97, 8.04, 9.09, 10.11% and 11 wt% were designated as S{sub 1}, S{sub 2}, S{sub 3}, S{sub 4}, S{sub 5}, respectively. The synthesized superabsorbent hydrogel were used for the adsorption of Cu{sup 2+}, Pb{sup 2+}, Fe{sup 2+} and MB and CV dyes from their aqueous solutions. The binding capacity for Cu{sup 2+}, Pb{sup 2+}, Fe{sup 2+} ions were 311 mg/gm/L at 850 mg/L, 209 mg/gm/L at 850 mg/L and 197 mg/gm/L at 850 mg/L for initial ion concentration respectively and MB and CV dyes molecules were 323 mg/gm/L at 360 mg/L, 289 mg/gm/L at 360 mg/L for initial molecule concentration per gram of AAc/NaAlg/SH containing 9.09 wt% SH content. The adsorption data obeyed Langmuir sorption isotherms.
