Abstract UiO-66, a water-resistant zirconium-based metal–organic framework (MOF) with
ultra-high porosity, larger surface area and plentiful active sites, has an advantage over …

In aqueous systems, chromium usually exists in both trivalent and hexavalent oxidation
states, being Cr (VI) of particular importance and concern due to its great toxicity. Industrial …

We attempted to recycle mixed waste tea and coffee ground as alternative low-cost
adsorbents for Cr (VI) removal. The adsorption parameters optimized were: initial Cr (VI) …

The discovery and further development of biosorption phenomena provide a basis for a
whole new technology aimed at the removal of various pollutants or the recovery of valuable …

The use of engineered nanomaterials (ENMs) for environmental remediation, known as
nanoremediation, represents a challenging and innovative solution, ensuring a quick and …

The objective of this study was to investigate heavy metal contamination in four major
vegetable bases and determine the health risks of residents in the vicinity of the highly …

A biomatrix was prepared from rice husk, a lignocellulosic waste from agro-industry, for the
removal of several heavy metals as a function of pH and metal concentrations in single and …

Lignocellulosic materials have a very complex configuration that contains a variety of active
sites capable, in some cases, of adsorbing contaminants from water. Agave bagasse is a …
