Polycyclic aromatic hydrocarbons (PAHs) are a group of organic pollutants known for their
persistence and potential carcinogenicity. Effective removal techniques are required since …

In this work, the authors attempt to interpret the visible, infrared and Raman spectra of ferrate
(VI) by means of theoretical physical-inorganic chemistry and historical highlights in this field …

In recent years, the development of environmentally friendly solid catalysts derived from
sludge for the efficient removal of pollutants from wastewater has triggered widespread …

Neutralization and selective precipitation of chemical species are regarded as the most
promising techniques to actively treat and valorise acid mine drainage (AMD). In this study …

The focus of this study was to improve the Reverse Osmosis Cooling (ROC) process by
using CaCO3 for neutralization and selective recovery of Fe (OH) 3 at pH 3.5. By using a …

The mixture of 1: 1 waste orange and lemon peel activated carbon (WOLAC) by phosphoric
acid (H3PO4) activation agent was prepared and reported for the first time for the removal of …

The high concentration of sulphates is detrimental to the infrastructure of wastewater
treatment plants. Hence in this study, we present the application of electrocoagulation …

Chromite is formed in nature in ophiolitic layers and ultrabasic rocks through fractional
