This study introduces an innovative method of using activated carbon derived from orange peels incorporated into calcium alginate beads to remove lead from synthetic water efficiently. This novel approach demonstrates remarkable effectiveness in addressing lead pollution in water. Established techniques such as SEM and FTIR were employed to characterize the adsorbents created in the laboratories. Batch studies confirmed the lead adsorbed were conducted to evaluate the efficiency of lead removal, with the highest removal efficiencies achieved at pH 6.5 (90.3%), an adsorbent dose of 2 mg (90.3%), a contact time of 50 minutes (92.3%), and an initial lead solution concentration of 20 ppm (93.2%). The study employed various adsorption models, including Langmuir, Freundlich, and Tempkin models. The Langmuir model exhibited an excellent fit to the adsorption isotherm at 60 °C, as indicated by a high linear regression correlation coefficient. For the bioadsorption process, pseudo-second-order kinetics fits well (R2 = 0.9992). The analytical results verify that activated carbon from discarded orange peels and calcium alginate beads effectively removes Pb, offering an encouraging solution for water purification challenges.

“…Therefore, quantifying the concentration of heavy metals in commonly consumed vegetables and fruits is essential for assessing potential health risks [13][14][15][16] . There have been reports of heavy metal toxicity in the Jodhpur city [17][18][19] . However, continuous assessment of toxic metal ions in vegetables is very important for people's health.…”

Our study was conducted between January and September 2023, and aimed to evaluate the presence of toxic heavy metals in vegetables cultivated using effluent and sewage water in Jodhpur city. Eight vegetable samples were obtained from four distinct locations, and the concentrations of seven harmful heavy metals (Cu, Zn, Pb, Cd, Cr, Ni, and Fe) were examined. The initial analysis employed ICP-MS, followed by determining the concentration of heavy metals in the vegetables through atomic absorption spectrometry (AAS). The Heavy Metal Pollution Index (HPI) was computed to assess pollution levels at each site. Comparative analysis of vegetable samples using both ICP-MS and AAS indicated elevated levels of lead, cadmium, and chromium pollution in vegetables from all four sites. Calculations further confirmed the contamination of the sites with toxic heavy metals. The order of metal concentration based on allowable limits was Fe>Cd>Cr>Pb>Ni>Zn>Cu. The overall order of observed heavy metal concentrations site-wise was site 4 > site 3 > site 2 > site 1. Many samples were obtained from local vendors near residential areas and community markets frequented by the public. This highlights a crucial issue of heavy metal toxicity exposure to the general population, emphasizing urgent government action, including essential restrictions and measures, to address this pressing problem.
