A review. Soaring demand for technol. metals (e.g., Cd, Ni) and its ever-depleting primary resources ask for alternative recovery from secondary sources. Ni-Cd battery is one such source that can abridge the gap between demand and supply of such metals. Biogenic recovery, being environmentally benign, is explored for Cd and Ni recovery to manage the menace of spent Ni-Cd battery. Studies with 20, 40 and 60 mg/L Cd2+ initial concentrations in batch mode (in triplicates) at pH 7.0 ± 0.2, 30 ± 0.5°C and 120 rpm were conducted using sulfate-reducing bacteria for 10 days. Anal. of extracellular polymeric substance revealed that protein secretion was enhanced, thereby forming Cd-EPS binding. Biosolids were collected and freeze-dried for morphol. anal. viz. FESEM/EDX, PXRD and TEM, which revealed the formation of CdS nanoparticles (JCPDS card #00-042-1411) in range of 2-6 nm. Similarly, combined effect with 5, 10 and 20 mg/L Ni2+ at 20 mg/L Cd2+ were also investigated. Furthermore, to test the efficacy for real field application, spent Ni-Cd battery was dismantled and its powder was characterized, digested with concentrated HCl at 70°C and was fed in batch mode after cooling, wherein nanoparticles of Ni and Cd sulfides were formed that has potential as semi-conducting material. In addition to this study using 1-Iodopyrrolidine-2,5-dione, there are many other studies that have used 1-Iodopyrrolidine-2,5-dione(cas: 516-12-1Synthetic Route of C4H4INO2) was used in this study.
1-Iodopyrrolidine-2,5-dione(cas: 516-12-1) is used in the preparation of vinyl sulfones from olefins and benzenesulfinic acid. It acts as a source for I+ and involved in Hunsdiecker reactions for the conversion of cinnamic acids, and propiolic acids to the corresponding alfa-halostyrenes and 1-halo-1-alkynes respectively.
