“…Bimetallic nanoparticles can also find application as colorimetric sensors. For example, Kheibarian and colleagues synthesized Cu@Ag core-shell NPs using the aqueous extract Citrus paradisi peel as a reducing and stabilizing agent [137]. They successfully used the system for the selective colorimetric detection of Hg 2+ ions in an aqueous solution.…”

Human exposure to acute and chronic levels of heavy metal ions are linked with various health issues, including reduced children’s intelligence quotients, developmental challenges, cancers, hypertension, immune system compromises, cytotoxicity, oxidative cellular damage, and neurological disorders, among other health challenges. The potential environmental HMI contaminations, the biomagnification of heavy metal ions along food chains, and the associated risk factors of heavy metal ions on public health safety are a global concern of top priority. Hence, developing low-cost analytical protocols capable of rapid, selective, sensitive, and accurate detection of heavy metal ions in environmental samples and consumable products is of global public health interest. Conventional flame atomic absorption spectroscopy, graphite furnace atomic absorption spectroscopy, atomic emission spectroscopy, inductively coupled plasma–optical emission spectroscopy, inductively coupled plasma–mass spectroscopy, X-ray diffractometry, and X-ray fluorescence have been well-developed for HMIs and trace element analysis with excellent but varying degrees of sensitivity, selectivity, and accuracy. In addition to high instrumental running and maintenance costs and specialized personnel training, these instruments are not portable, limiting their practicality for on-demand, in situ, field study, or point-of-need HMI detection. Increases in the use of electrochemical and colorimetric techniques for heavy metal ion detections arise because of portable instrumentation, high sensitivity and selectivity, cost-effectiveness, small size requirements, rapidity, and visual detection of colorimetric nanosensors that facilitate on-demand, in situ, and field heavy metal ion detections. This review highlights the new approach to low-cost, rapid, selective, sensitive, and accurate detection of heavy metal ions in ecosystems (soil, water, air) and consumable products. Specifically, the review highlights low-cost, portable, and recent advances in smartphone-operated screen-printed electrodes (SPEs), plastic chip SPES, and carbon fiber paper-based nanosensors for environmental heavy metal ion detection. In addition, the review highlights recent advances in colorimetric nanosensors for heavy metal ion detection requirements. The review provides the advantages of electrochemical and optical nanosensors over the conventional methods of HMI analyses. The review further provides in-depth coverage of the detection of arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) ions in the ecosystem, with emphasis on environmental and biological samples. In addition, the review discusses the advantages and challenges of the current electrochemical and colorimetric nanosensors protocol for heavy metal ion detection. It provides insight into the future directions in the use of the electrochemical and colorimetric nanosensors protocol for heavy metal ion detection.

“…(Yu and Lin, 2016) The compounds Mg 2+ and Mn 2+ are metal ion compounds commonly found in their salt forms (MgSO4 and MnSO4), in the form of their metal oxides (MgO and MnO), or as part of naturally occurring mineral compounds. Magnesium (Mg 2+ ) is a silvery-white metal that is insoluble in cold water (Kheibarian et al, 2022), while manganese (Mn 2+ ) is a white-grayish metal classified as a heavy metal (atomic mass = 54.94 g/mol)…”

This research aimed to determine the most effective adsorbent for reducing Mg2+ and Mn2+ levels in residential water near the oil and gas industry in the Tambun area, Bekasi, Indonesia. Bentonite was tested with varying temperature conditions. The study further compared activated charcoal and bentonite as potential adsorbents, examining their efficacy under different contact times (10, 20, and 30 minutes). Thus, sampling followed the SNI 6989.57:2008 method for surface water sampling, with bentonite conditioning and activation as initial steps. Next, the adsorption experiments utilized a separating funnel, varying the contact time between adsorbent and sample. Hence, the filtrates were analyzed quantitatively for Mn2+ using atomic absorption spectroscopy and for Mg2+ through complexometric titration.
