The samples were digested using 10 ml of nitric acid at 120-150 ℃, and 2 ml of Perchloric acid was added after attaining room temperature, it was digested further until a clear solution was obtained, then made up to 25 ml with distilled water. The concentration of lead, cadmium, iron, and zinc were determined and quantified using Atomic Absorption Spectrophotometry (AAS), and the health-associated risks of these metals were evaluated using the standard Target Health Quotient (THQ).</p> <p><strong>Results: </strong>The EDI (Estimated Daily Intake) of lead (Pd), Cadmium (Cd), iron (Fe), and zinc (Zn) was 0.130, 0.001, 0.726, and 0.193 mg/l, respectively, all were within the World Health Organization (WHO)-acceptable range. The Chronic Daily Intake (CDI) of Pd, Cd, Fe, and Zn was obtained as 0.001 to 0.010, 5.7 x 10<sup>-5</sup>, 0.001 to 0.050, and 0.0001 to 0.010 mg/l respectively.</p> <p><strong>Conclusion: </strong>THQ for all metals analyzed was&lt;1, the WHO acceptable limit. All the heavy metals were within acceptable THQ limits, thus posing no carcinogenic health potential risks on long-term consumption.</p> SAMUEL J.

The presence of heavy metals and dyes in water bodies are deadly to the living organisms inside water, in which these pollutants are bio-accumulated and biomagnified in the environment. Due to the health effects of these pollutants, it is, therefore, necessary to treat metal and dye-contaminated wastewater prior to its discharge into the environment in order to comply with the stringent environmental regulations and also safeguard the present and future generations.</p> <p><strong>Methods</strong>: The influence of pH, contact time, initial metal concentration, adsorbent dosage and temperature were studied in batch experiments at room temperature and were measured using UV-VIS Spectrophotometer at wavelength 464 nm. Fourier Transform Infrared (FTIR) technique was employed as an instrument for characterization of the adsorbent before and after adsorption and the data were collected and interpreted using Microsoft Excel, 2016.</p> <p><strong>Results</strong>: Maximum sorption for methyl orange was found to be at pH 2. The adsorption was rapid at the first 90 min of contact, with uptake of more than 90%, and equilibrium was achieved in 60 min of agitation. Langmuir, Freundlich and BET’s isotherm models were applied to describe the adsorption of methyl orange dye. Fourier Transform Infrared (FTIR) spectra of ceramics powder revealed that OH, C-H, C=C, C-O stretching were responsible for the adsorption. However, the effects of different experimental parameters that influenced the efficiencies of the adsorbent have been evaluated and optimized.</p> <p><strong>Conclusion</strong>: The investigation revealed that the adsorption capacity of the powdered ceramics on the removal of methyl orange dye is high enough compared to observed values in literatures. Freundlich’s model fitted the equilibrium data better, while the pseudo-second-order kinetic model was the most fitting from the kinetic data obtained for the adsorption of methyl orange dye.</p> OLALEYE TIMILEHIN F., OGUNBIYI OLUWAGBENGA J., JEMKUR MAURICE Copyright (c) 2023 OLALEYE TIMILEHIN F., OGUNBIYI OLUWAGBENGA J., JEMKUR MAURICE Sun, 01 Oct 2023 00:00:00 +0000
