“…Several studies deal with the extraction of metals (mainly Li and Co) from disposed LIBs using different extractant agents such as inorganic acids (H 2 SO 4 , HCl, HNO 3 or H 3 PO 4 ) and (as an alternative with lower negative impact on the environment) organic acids (succinic acid, maleic acid, citric acid, ethylenediaminetetraacetic acid (EDTA), ascorbic acid, tartaric acid or acetic acid).…”

Electrodialytic remediation has been widely applied to the recovery of different contaminants from numerous solid matrices, solving emerging issues of environmental concern. Results and conclusions reported in studies about real contaminated matrices are summarized in this work. The influence of pH value on the treatment effectiveness has been widely proved, highlighting the phenomenon of ‘water splitting’ in the membrane surface. This dissociation of water molecules is related to the ‘limiting current’ which it is desirable to exceed at the anion exchange membrane in order to produce the entering of protons toward the solid matrix. Other important parameters for the optimization of the technique, such as the current density and the liquid/solid ratio, are also discussed through the revision of studies using real solid matrices. This work also focuses on the pioneer proposal of electrokinetic technologies for the recycling of lithium ion batteries, considering the relevance of waste properties in the design and optimization of the technique. From a thorough literature revision, it could be concluded that further experimental results are needed to allow an optimal application of the technique to the rising problem of residues from batteries. The main aim of this work is to take the first steps in the recovery of valuable metals such as Li and Co from spent batteries, incorporating principles of green chemistry. © 2019 Society of Chemical Industry

“…Reciklažne tehnologije koje se primenjuju pri tretmanu Li-jonskih baterija generalno se mogu podeliti na: pirometalurške, hidrometalurške i biološke metode [3]. Sa aspekata zaštite životne sredine i potrošnje energije, prednost treba dati hidrometalurškim i biološkim procesima [4]. Bez obzira na to koja od navedenih metoda se primenjuje, pre samog postupka reciklaže, neophodno je upoznati se sa strukturom baterija i toksičnošću pojedinačnih komponenti.…”

Toksičnost osnovnih komponenti u Li-jonskim baterijama IZVOD Li-jonske baterije sadrže veliki broj štetnih komponenti, čije prisustvo u životnoj sredini može izazvati neželjene posledice po zdravlje ljudi. Primenom inovacija u tehnologiji reciklaže Li-jonskih baterija može se postići značajan stepen zaštite ljudi i životne sredine uopšte. Međutim, opasnost od ekspolozije i oslobađanja toksičnih materija ne može biti isključena čak ni u slučaju primene najnovijih modernih tehnologija. U cilju blagovremenog prepoznavanja potencijalnih opasnosti, u ovom radu je opisano moguće toksikološko dejstvo najvažnijih komponenti Li-jonskih baterija, sa posebnim akcentom na upotrebljene elektrolite. Takođe, predložene su i određene mere predostrožnosti prilikom reciklažnih postupaka, a koje bi u znatnoj meri poboljšale bezbednost uposlenih lica.

BACKGROUND Phosphor in discarded cathode ray tube (CRT) contained valuable metals, yttrium (Y) and europium (Eu), which are categorized as technology‐critical elements (TCEs) in terms of their supply risk and importance in emerging technologies. Microwave‐assisted leaching was applied to recover Y and Eu from waste CRT with sulfuric acid (H2SO4) solution as the leaching agent in the current study. It is aimed to develop an alternative leaching method of valuable metals from waste CRT phosphor. RESULTS The effects of microwave power and acid concentration on leaching efficiency of Y and Eu were investigated. Shrinking‐core model could describe the leaching kinetics of Y and Eu well and it was controlled by chemical reaction and diffusion through the product layer. Higher leaching efficiency was found when microwave power increased from 200 to 600 W, and was also found as acid concentration increased from 0.5 to 2 mol L−1. Leaching efficiency of Y and Eu were 78.07% and 100%, respectively, for Y and Eu within 60 min at microwave power of 400 W, using 2 mol L−1 of H2SO4 at 10 g L−1 of solid to liquid ratio. Compared with conventional leaching, microwave‐assisted leaching is an alternative technology that could shorten reaction time significantly. CONCLUSIONS The concentration of acid and microwave power affected microwave‐assisted leaching of Y and Eu from waste CRT phosphor. Microwave‐assisted leaching could be an alternative process for rare earth elements recovery. © 2019 Society of Chemical Industry
