Multidentate amine ligand decorated hairy brushes on PS-DVB microbeads for Cd(II) removal from water samples

ABSTRACT

Cadmium is one of the leading pollutants due to its persistence and high mobility in the environment. In this work, the sorption behavior of cadmium ions were investigated using a newly synthesized adsorbent, multidentate amine ligand decorated hairy brushes on PS-DVB microbeads. The adsorption parameters were examined to evaluate the optimum values for pH, contact time, temperature and adsorbent amount (pH of 7.0, 5.0 mg adsorbent amount, 60.0 min. contact time, 25°C). The adsorption process well fitted with Langmuir isotherm and pseudo-second order model. The promising results indicated that the sorbent is a good alternative in cadmium removal studies.

Novelty statement

Novelty of the present work includes the following items: synthesis, characterization and application of a sorbent, ethyl diethylene triamine modified poly(oligo (ethylene glycol) methacrylate)-block-poly(glycidyl methacrylate) (POEGMA-b-PGMA) grafted polystyrene-divinylbenzene (PS-DVB) microbeads and removal of cadmium ions from aqueous solutions using inductively coupled plasma mass spectrometry. The sorbent is an alternative material for cadmium remediation and is economic and environmental friendly. The proposed sorbent offers a great potential for cadmium removal with promising properties in terms of chemical stability, high sorption capacity with good accuracy and precision.
