Abstract Statistical analysis is essential for minimizing the time, cost, and number of experiments needed to get maximum output. In this work, removal cadmium bivalent (Cd (II)) ions was optimized using Box‐Behnken design methodology. The effects pH, concentration, temperature were investigated cadmium. Maximum (85.70 %) achieved at pH 5.34, initial Cd(II) concentration 46.61,contact time 166.09 (min), 59.40 °C on Punica Granatum carpellary membrane powder (PGCMP) 88.61 % its modified forms (MPGCMP) 5.79, 65.70,contact 178.96, 59.91 temperature. model validated by analyzing variance (ANOVA). practical data well fitted quadratic model. PGCMP MPGCMP found be naturally occurring, environmentally friendly adsorbents mitigation Cd (II) as other toxic heavy metals from drinkable or wastewater.

This study focused on fluoride (F−) contamination of water sources in Bahimi village, Cameroon. After the first investigation, results revealed that all samples collected had elevated concentrations ions (2.3 ± 0.1) mg/L to (4.5 0.2) above WHO guidelines (less than 1.5 mg/L). To mitigate F− levels, use bone char (BC) as an adsorbent material was proposed and its performance tested. BC prepared from bovine bones at different calcination temperatures (350 °C, 450 550 °C 650 °C) residence times (1 h 2 h). The materials were characterized detail by SEM/EDS, BET, FTIR, XRD. BET findings indicated surface area decreased with increasing temperature time. At a lower heating holding time 1 h), exhibited higher specific (112.3 0.3) m2/g adsorption capacity for sampled water. Also, batch experiments showed optimized dose 8 g/L facilitates reduction level below acceptable limit (1.5 mg/L) within 5 min treatment. presence Ca2+ Mg2+ natural has positive effect removal resulting high range (72.5 1.4)% (80.3 0.6)%. It found occurs via cation exchange Na+. However, increase dissolved organic carbon (DOC) treated limited application BC. Overall, presented cost-effective this recalcitrant ion source.

Exposure to arsenic (As) can induce numerous lethal diseases, such as cancer, cardiovascular issues, skin and diabetes in humans. The major route of human animal exposure As is through drinking As-rich groundwater. This study assessed occurrence the groundwater two districts Punjab (Vehari Lodhran) provinces Pakistan. Groundwater analysis revealed an average concentration 7.7 µg/L (n = 79) area, with a maximum up 41.4 (33% samples exceeding WHO limit 10 µg/L). Arsenic traces were found milk 15, mean: 0.79 µg/L, 17% 2.0 µg/L), hair 12, 0.36 µg/g, 1.0 µg/g), nails 8, 0.03 none exceeded µg/g). Health risk assessment indices that about 33% hazard quotient 54% cancer factor their thresholds. Despite low–moderate accumulation few biological samples, there possibility potential poisoning via long-term continuous use for drinking. Monitoring blanket testing wells well water provide baseline data minimize threat As-mediated arsenicosis As-affected areas Moreover, detailed higher number recommended area.
