Separation of cadmium and lead from wastewater using supported liquid membrane integrated with in-situ electrodeposition

Development of an efficient electrochemical process for removing and separating soluble Pb(II) in aqueous solutions in presence of other heavy metals: Studies of key parameters

“…According to the same way, experiments were performed in presence of other heavy metals, such as Cd (II) or Ni (II) or Cu (II) at an equivalent concentration than that soluble lead, to study their effect on the removal efficiency of lead and their possible separation. Indeed, this point is particularly important because the separation of lead with other heavy metals is generally complicated and required complex chemical and/or physical processes [35][36][37]. Finally, a test was carried out at laboratory scale on an effluent coming from a WWTP to evaluate the real interests of this very simple process for purification of wastewaters containing soluble lead.…”

Removal of hexavalent chromium from wastewater using supported liquid membrane: synthesis of chromium‐iron complex through electrochemical reaction

“…In this context liquid membrane (henceforth referred as LM) technology is proved to be very promising technology to separate chromium from wastewater. Interested readers may go through the published literatures of this research group regarding separation of heavy metals using LM based techniques (Chakrabarty et al, 2009(Chakrabarty et al, , 2010a(Chakrabarty et al, , 2010bBhatluri et al, 2013Bhatluri et al, , 2014Bhatluri et al, , 2015Bhatluri et al, , 2015bBhatluri et al, , 2017. Use of environmentally and physiologically benign vegetable oils in the organic phase of the LM is one of the major and crucial merits of these works, which makes the process green in nature.…”

“…Sánchez et al (2018Sánchez et al ( , 2019 focused on the removal of Cr(VI) ions from aqueous solution membrane based processes. Bhatluri et al (2015aBhatluri et al ( , 2017 and Mondal et al (2019) had proposed a novel method where separation of heavy metal were carried out by SLM with in situ electro deposition technique inside strip phase. The said process helps extracted heavy metal simultaneously deposited on the cathode placed inside the strip phase.…”

Detection of Cd (II) and Pb (II) by anodic stripping voltammetry using glassy carbon electrodes modified with Ag-Hg and Ag-Bi bimetallic alloyed

“…However, those low levels must be accurately known in order to start a study regarding the extent of a possible contamination process by these two elements as a function of time. Evaluation of electrochemistry-based techniques together with the best way of preconcentration and isolation of heavy metals for their accurate determination have been the goal of several research studies (Zhu et al, 2006;Liang et al, 2005;Abkenar et al,2010;Abkenar et al, 2011;Hosseini et al, 2010;Dahaghin et al, 2017a,b;Bagheri et al, 2012;Huang et al,2014;Huang et al, 2011;Bhatluri et al, 2017). Among the electrochemistry techniques most widely used for Cd and Pb determination, based on their high sensitivity and freedom from matrix effects, anodic re-dissolution voltammetry (ASV) is one of the most convenient.…”
