A Suitable Method for Removing of Heavy Metal Ions from Aqueous Solutions Using Proper Copolymer and its Derivations

Abstract

Synthesis of copolymers such as poly (styrene alternative maleic anhydride) (SMA), (SMA+ Melamine +1,3-diaminopropane) (CSMA-M), (CSMA-M + propanedioic acid) (CSMA-MP) and (CSMA-M + butanedioic acid) (CSMA-MB) for removing heavy metal ions from aqueous solutions. Adsorption of Cd (II), Pb (II) and Zn(II) on modified copolymers and adsorption behavior of these heavy metal ions on the adsorbents were studied by altering the characters such as pH, adsorbent dose, contact time, and heavy metal ions concentration. Adsorption percentage was increased by increasing each of these parameters. The isotherm models such as: Langmuir, Freundlich, Temkin, and Dubinin-Radushkevich were applied to illustrate adsorption equilibrium. The outcomes shown that the best consistency was accessed with the Langmuir isotherm equation, production maximum adsorption capacities of these adsorbents are very suitable for removing heavy metal ions from aqueous solutions. The adsorbents were characterized by Fourier transform infrared spectroscopy scanning electron microscopy and X-ray diffraction analysis.

Synthesized Nano particle derivation of poly (Styrene – co- Maleic Anhydride) and sour cherry Rock for removing nickel (II) ion from aqueous solutions

“…The desorption ratio (D%) of Nickel (II) ions from the CSMA-MO and PCR was computed with the following equation:D%=Ca Va()Co - CeV× 100 Where V is the volume of the solution (L); C a is the concentration of the Nickel (II) ions in the desorption solutions (mg/L), and V a is the volume of the desorption solution (L). Desorption of Nickel (II) ion from The CSMA-MO– Nickel (II) ion and PCR- Nickel (II) ion complexes are 99% and 98.5%, respectively [[37], [38], [39], [40], [41], [42]]. The raked CSMA-MO and PCR from the desorption process was leached thoroughly with deionized water and dried by vacuum pump at 65 °C for reuse [[43], [44], [45]].…”

“…Продукти модифікації SMA виявили здатність до ефективної сорбції тяжких металів із водних розчинів [14]. Зокрема, шляхом модифікації аліфатичними моно-і діамінами отримано матеріал, шо має сорбційну ємність за ураніл-іонами із сульфатних розчинів на рівні 62 мг•г -1 в певному інтервалі рН [15].…”

Microbiological Reduction of Molybdenum to Molybdenum Blue as a Sustainable Remediation Tool for Molybdenum: A Comprehensive Review

“…A considerable and indiscriminate release of pollutants into the environment has occurred in parallel with the growing population and intensity of industrialization [6,7]. Harmful effects on human health and biota can be exerted when heavy metals reach levels above the critical load [8][9][10][11]. In their elemental forms and different combinations, metals such arsenic, cadmium, chromium, cobalt, copper, lead, 2 of 25 mercury, molybdenum, nickel, silver, and zinc are known to be toxic [12][13][14], and they are also non-degradable [15].…”
