Research trends of heavy metal removal from aqueous environments

A Bibliometric and Visualized Overview for the Evolution of Process Safety and Environmental Protection

“…The tool has several functions for bibliometric mapping, including collaboration analysis (e.g., authors, institutions, and countries/regions), topics analysis (e.g., keyword or terms), and citation-based analysis (e.g., bibliographic coupling and co-citations). Several papers have already applied VOSviewer to do bibliometric mapping analysis in environmental protection and safety-related topics, such as climate change [ 29 ], heavy metal removal [ 30 ], carbon emissions [ 31 ], contamination of water bodies [ 32 ], carbon capture and storage [ 33 ], soil remediation [ 34 ], safety culture [ 25 ], construction safety [ 35 , 36 ], process safety [ 37 ], domino effect [ 38 ], laboratory safety in universities [ 39 ], road safety research [ 40 ], etc.…”

Electrocoagulation removal of Pb, Cd, and Cu ions from wastewater using a new configuration of electrodes

“…Heavy metals are non- degradable and not converted to more simple forms, like organic pollutants. They are also toxic due to their effects on living organisms, easy bioaccumulation in the food chain, and comprehensive sources [1 , 2 , 10] . The wastewater is classified as water-toxic metal pollution when it is polluted by high-density elements with (63.5 to 200.6) atomic weight or an atomic number greater than 20 and a weight density greater than 5 g/cm 3 [1] , [2] , [3] , 11] .…”

Constructed Wetlands as Treatment Systems: An Overview and Bibliometric Analysis

“…Nowadays, similar studies are conducted in a variety of sectors of research, including but not limited to environmental sciences and engineering (Nazaripour et al, 2021;Su et al, 2022), business and accounting (Ferreira et al, 2022), biological sciences (Biancone et al, 2022), medicine (Sweileh, 2022), chemical engineering (Ebrahimi et al, 2022), pharmacology (Sweileh, 2021), psychology (Vogl et al, 2018), and physics (Saparini et al, 2021).…”
