Summary: The novel solid-supported ionic liquid (Si-Sal-SSIL) was synthesized by immobilizing [MTMSPI][Sal] onto activated silica gel. The [MTMSPI][Sal] was prepared from the reaction of [MTMSPI][Cl] with sodium salicylate and characterized. Si-Sal-SSIL showed superior removal capacities for Pb(ii) and Ni(ii) ions compared to native silica gel. Si-Sal-SSIL was successfully used as a solid adsorbent for the efficient removal of Pb(ii) and Ni(ii) from aqueous solution.

Summary: The accumulation of both natural and anthropogenic sources of metals in the ecosystem has led to increasing concerns over heavy metal (HM) pollution. Human exposure to HMs, such as mercury, arsenic, lead, chromium, and cadmium, has become a significant environmental and health issue. These HMs can cause acute or chronic poisoning through water, air, or food. Their bioaccumulation in the body leads to various toxic effects on organs and tissues, primarily through the production of reactive oxygen species, enzyme inactivation, and oxidative stress. Conventional techniques for HM removal are limited, especially when the HM concentration is low. Microbial bioremediation, utilizing organisms like fungi and bacteria, has emerged as a potential solution due to their superior biosorption and bioaccumulation capabilities. This review aims to provide insights into HM uptake, toxicity mechanisms, and the management of metal poisoning through the selection of microbial remediation technology.

Summary: The thermal adsorption residue (TDR) derived from oil sludge co-contaminated soil was found to effectively neutralize acid substances and adapt to a wide pH range. It demonstrated high adsorption capacities for four heavy metals, namely As(III), Zn(II), Cu(II), and Cd(II). There was a competitive adsorption among the three cations on TDR, and the presence of As(III) lowered the adsorption capacity of Zn(II), Cu(II), and Cd(II).

Summary: Nitration is a chemical process that introduces a nitro group into a molecule, which modifies properties of organic compounds. Elevated nitrate levels in copper mining have operational difficulties and impact the recovery percentages and organic extractants. Various methods have been developed to address the issue, including the use of additives and recirculation approaches. The study highlights the effectiveness of the TAP Test in assessing nitrate aggressiveness and suggests an increase in usage of these tests in hydrometallurgical plants.

Summary: This study investigates the effect of Mn doping on the crystalline structure of hydroxyapatite (Hap) synthesized by the hydrothermal method. X-ray diffraction analysis reveals that the average size of crystallite decreases from 23.67 nm to 22.69 nm as the Mn concentration increases. Transmission electron microscopy shows two distributions of particle sizes in all samples. Fourier transform infrared analysis confirms the presence of characteristic absorption bands of PO4-3 and OH- groups in Hap. A substitution mechanism between Mn and Ca+2 ions of Hap is established. The cell viability test demonstrates that Hap with 1.5%wt Mn concentration exhibits non-cytotoxic behavior according to ISO 10993-5. Moreover, the materials exhibit good osteoinductive properties as shown by histology and immunofluorescence expression of osteogenic markers.
