RETRACTED: Immobilization of 5-amino-1,3,4-thiadiazole-thiol onto kanemite for thorium(IV) removal: Thermodynamics and equilibrium study

Amazon kaolinite functionalized with diethylenetriamine moieties for U(VI) removal: Thermodynamic of cation-basic interactions

“…The adsorption experiments were performed through the batchwise method by suspending a series of 20 mg samples of the solid, in 20.0 cm 3 aqueous solutions of cations at concentrations varying from 1.25 × 10 −2 to 3.00 × 10 −1 mmol dm −3 , under orbital stirring for 24 h at 298 ± 1 K [16,17]. Profiles of the obtained adsorption isotherms were represented by the number of moles adsorbed (N f ), versus the number of moles at equilibrium per volume of solution (C S ), for series of isotherms, the data reveal that the adsorption process conforms to the Sips model (Eq.…”

Retraction Notices are Increasing in Scientific Journals!

“…Elsevier in one of his biggest move has announced to retract about eleven research papers published in different Elsevier Journals from Brazilian research group led by Claudio Airoldi stating the Elsevier policy behind article withdrawal [11]. Later, Journal of Colloid and Interface Science in 2011 has published retraction notice incorporating all eleven research papers to bring this fraud publicly [12].…”

“…When I login to web of science (Thomson Reuters) to get citation information of Claudio Airoldi's falsified research papers, I found that one of his paper was cited 35 times and an overall 37 times [13]. Interestingly, even after publication of retraction notice [11], one of his students whom he wrote many papers is still citing the work in a recent publication [14]. Most of the above listed retractions were appeared after many years of publication of the original paper.…”
