Abstract:
In this study, a description was given for the adsorbent CaSiO3 for allure proximate examination and determination like particle
density, main part density, and porosity analysis. ,is is performed before management of batch adsorption experiments. Both
kinetics and balance studies for the adsorbent were examined. ,e influences of various process parameters like lead con centration, pH, adsorbent dosage, and contact temporal length for process removal were explored. ,e removal efficiency of CaO
from eggshell was enhanced to increase after mixing it with silica coagulate compared with added scholar’s findings for the same
limit. ,e maximum removal efficiency (99.58%) was obtained by limiting the pH, adsorbent dosage, initial lead concentration,
and contact time at 4, 1.8 g, 35 g/L, and 140 minutes, respectively. ,us, blending CaO from eggshells with silica gel can increase
the adsorption competency of CaO. Lead removal is well integrated into the Langmuir isotherm model with an equivalent factor of
0.991. ,e kinetic data of adsorption fit well into a pseudo-first-order model with a correlation coefficient of 0.90111. ,e pseudo second-order model was the rate-determining step involved in the lead adsorption process for calcium silicate
(CaSiO3) adsorbents.
