High reactive nano zero-valent iron produced via wet milling through abrasion by alumina
(2019-06-15)
Article
Open AccessThe performance of new nano zero-valent iron (nZVI) particles produced by a promising new milling method in organic solvent was examined. The basic feature of the new process involves the addition of abrasive alumina ... -
Integration of membrane distillation as volume reduction technology for in-land desalination brines management: Pre-treatments and scaling limitations
(2021-07)
Article
Restricted access - publisher's policyManagement of in-land reverse osmosis (RO) desalination brines generated from surface brackish waters is a current challenge. Among the different near-Zero and Zero Liquid Discharge (ZLD) alternatives, Membrane Distillation ... -
Rare earth elements recovery from secondary wastes by solid-state chlorination and selective organic leaching
(2021-03-01)
Article
Restricted access - publisher's policyProcessing of end-of-life products (EoL) containing rare earth elements (REE) has gained increasing importance in recent years with the aim of avoiding supply risks. In addition, circular economy renders complete recirculation ... -

(Elsevier, 2021-08-13)
Article
Restricted access - publisher's policyThis study is focused on the recovery of polyphenols from vegetable and fruit residues and further evaluation of antioxidant features of extracts. Spinach and orange have been selected as representative matrices for a more ... -
Integration of membrane technologies to enhance the sustainability in the treatment of metal-containing acidic liquid wastes. An overview
(2021-06-15)
Article
Restricted access - publisher's policyThe mining and hydrometallurgical industries generate effluents characterised by a high acidity (pH < 3) and a high content of metals (e.g. Fe, Al, Cu and Zn, among others) and non-metals (e.g. As, Sb, Bi), which confers ... -
Diffusion dialysis for the treatment of H2SO4-CuSO4 solutions from electroplating plants: Ions membrane transport characterization and modelling
(2021-07)
Article
Restricted access - publisher's policyDiffusion dialysis (DD) is proposed to separate and recover mineral acids and transition metals from electroplating industry process waters promoting a circular approach of resources recovery. In this work, a DD module ... -
Valorisation options for Zn and Cu recovery from metal influenced acid mine waters through selective precipitation and ion-exchange processes: promotion of on-site/off-site management options
(2021-04)
Article
Restricted access - publisher's policyAcid mine waters (AMWs), generated in the processing of polymetallic sulphides, contain copper and zinc as the main valuable transition metal ions, which are typically removed by liming, due to their great environmental ... -
Nitrate and nitrite reduction by ferrous iron minerals in polluted groundwater: Isotopic characterization of batch experiments
(2020-08-20)
Article
Restricted access - publisher's policySince nitrate (NO3-) has been related to human health and environmental problems, safe and sustainable strategies to remediate polluted water bodies must be investigated. This work aims to assess the feasibility of using ... -
