Abstract:
Worldwide, industries and their locations are a significant source of water pollution, with
nitrates having the most harmful impacts. Nitrate removal from water requires productive
technique to solve this issue. Chitosan beads, a non-toxic, biocompatible, and biodegradable
polymer have demonstrated significant promise in a variety of applications, such as the
elimination of various salt ions and heavy metals from water. In this work, algal synthesized
Manganese dioxide nanoparticles were created which were then embedded in chitosan to create
beads. For nitrate adsorption from mine water, the effectiveness of Manganese dioxide embedded chitosan beads in a batch system has been investigated. Physiochemical properties
of MnO2 nanoparticles were characterized through UV vis spectrophotometry, XRD, SEM,
FTIR, and EDX. Multiple factors influencing the adsorption attitude of hybrid beads such as
adsorbent dosage, initial concentration, pH, and the interaction time of Nitrate ions were
measured. In this study, pseudo-second-order kinetics best suit the experimental data. The
results indicated that beads of Manganese dioxide-impregnated chitosan beads showcase
efficient performance and benefits in Nitrate removal from the mine water, providing a
sustainable, cost-effective, and eco-friendly solution.
