Abstract
A novel bio-based resin, Tamarind Triazine Glutamic Acid (TTGA), was synthesized
through the chemical modification of tamarind seed polysaccharide with triazine
and glutamic acid moieties. This study aims to develop a sustainable and eco-friendly
resin with potential applications in water treatment, metal ion adsorption and biomedical
fields. The resin was characterized using Fourier Transform Infrared (FTIR) spectroscopy.
Its ion-exchange capacity, thermal stability and adsorption performance for heavy
metals (Fe²⁺, Zn²⁺, Cu²⁺, Pb²⁺, Cd²⁺ and Cr³⁺) were evaluated. The TTGA resin demonstrated
promising properties, underscoring its utility as a biodegradable and functional
alternative to synthetic resins. Industrial effluent containing heavy metal ions
can be selectively separated using TTGA resin.
The distribution coefficient (Kd) of metal ions at various pH values was investigated
using the batch equilibration method. Investigations were conducted into the effects
of adsorbent dosage, treatment duration and pH on the removal of heavy metal ions
from industrial effluent. The resin can be repeatedly regenerated and is adaptable
to continuous processes.
