“…Elements used in crystal glass, such as arsenic (As), cadmium (Cd), antimony (Sb) and lead (Pb) end up in the environment through emissions, effluents and other factory wastes (Mutafela et al 2020b). They can contaminate soil, surface and ground water, and pose human health hazards (Keng et al 2014;Malik et al 2019). In Sweden, contaminated glass dumps are excavated and materials landfilled as a remediation measure.…”

Glass waste dumps from crystal glass production is an health issue due to the occurrence of antimony, arsenic, cadmium and lead in crystal glass. Recovery of those elements could both decrease pollution and recycle metals in the circular economy. Pyrometallurgy is a potential recovery method, yet limited by high energy consumption. Here we tested a lower-energy alternative in which glass is mechanically activated in a ball mill and leached with nitric acid. Results show that mechanical activation destabilised the glass structure and resulted in 78% lead extraction during leaching at 95 °C. Temperature had the most significant effect on extraction, whereas acid concentration, from 0.5 to 3 M, and leaching time, from 0.5 to 12 h, had insignificant effects. In each experiment, 75% of the final extracted amount was achieved within 30 min. The study demonstrates potential for lead extraction from glass waste at lower acid concentration, shorter leaching time and lower temperature, of 95 °C, than traditional pyrometallurgical extraction, typically operating at 1100 °C.

The treatment of heavy metal-contaminated wastewater is an important action to reduce The negative impacts of industrial wastes on water bodies. This work focuses on The application of a low-cost titanium (IV) phosphate sorbent of TiO(OH)H2PO42H2O chemical composition toward lead and zinc ions depending on their concentration and The temperature of The solution. The kinetic studies showed that The values of The rate of intraparticle diffusion and The effective diffusion coefficients for Zn2+ were considerably higher than those for Pb2+. To explain The difference between The sorption kinetics rates for Pb2+ and Zn2+, The effective radius and dehydration degree of The adsorbed ions were calculated. The sorbent capability of The lead and zinc ion removal and its excellent efficiency in The presence of a high concentration of calcium ions were demonstrated using simulated mine water. Due to The fast kinetics and The high exchange capacity of titanium phosphate toward divalent ions, this sorbent can be considered as a promising material for The concentration and immobilization of heavy metals into The phosphate matrix.

“…Nowadays, the monitoring of toxic effects becomes mandatory since water resources are being scarce, and the development of monitoring tools is essential for an easy, fast, and accurate detection of heavy metals in a few steps. Sensing is an integral part of both fast and conventional measurement methods for the quantification of heavy metals proposed in nowadays research [20]. Nanotechnology used in sensing improves not only the efficiency but also the selectivity and reduces the time needed in each step of the methodology of quantification of heavy metals in water.…”

A nanostructure is a system in which at least one external dimension is in the nanoscale, it means a length range smaller than 100 nm. Nanostructures can be natural or synthetic and determine the physicochemical properties of bulk materials. Due to their high surface area and surface reactivity, they can be an efficient alternative to remove contaminants from the environment, including heavy metals from water. Heavy metals like mercury (Hg), cadmium (Cd), arsenic (As), lead (Pb), and chromium (Cr) are highly poisonous and hazardous to human health due to their non-biodegradability and highly toxic properties, even at trace levels. Thus, efficient, low-cost, and environmentally friendly methodologies of removal are needed. These needs for removal require fast detection, quantification, and remediation to have heavy metal-free water. Nanostructures emerged as a powerful tool capable to detect, quantify, and remove these contaminants. This book chapter summarizes some examples of nanostructures that have been used on the detection, quantification, and remediation of heavy metals in water.
