Fruit processing industries generate millions of tons of
organic waste annually, often improperly disposed of at
open landfills. Based on the circular economy and waste
management concepts, reusing these bio-waste materials
is one of the future sustainable demands. Furthermore,
recent investigations have shown that this material type
can be reused as high-quality sorbents, with certain
modifications that should be applied. Considering this,
we have investigated the possible application of lignocellulosic
waste-peach stones (Prunus Persica L.),
immobilized in sodium alginate, as heavy metals sorbent.
The immobilized particles (IPS) were utilized to
remove metals from synthetic water solutions. Among
all metals (Pb, Cu, Cd, and Zn), IPS has shown superior
performance in Pb removal, governing further investigations.
Dried IPS spheres were characterized by FTIR,
SEM/EDX, and TG techniques. The batch reaction system
investigated the effects of the contact time, initial
Pb ...concentration, and mass-to-volume ratio. Optimized
operational parameters were used in kinetic and isotherm
studies. Obtained data were modeled using a
nonlinear form of pseudo-first, pseudo-second, Elovich,
Freundlich, and Langmuir equations. The results showed
pseudo-second-order kinetics with Freundlich isotherm
fitting Pb removal, indicating a heterogeneous IPS surface
with the multilayer adsorption and adsorbed molecule
interaction. As obtained from Langmuir isotherm,
IPS particles have removed Pb by saturation capacity of80.40 mg Pb/g. These preliminary results indicate that
IPS can be applied to purify waters contaminated with
lead metal.
