Arsenic removal from drinking water by electrocoagulation using iron electrodes-an understanding of the process parameters(Journal of Environmental Chemical Engineering ) (Banerji, Tuhin,4,4,3990-4000,Year : 2016)

Various methods exist for arsenic removal from water, but most are not viable as they require addition of oxidants and use adsorbents which have limited adsorption capacities. Electrocoagulation using iron electrodes (ECFe) is a promising technology for arsenic removal. Efficiency of arsenic removal by ECFe may be affected by parameters such as pH, current intensity, initial arsenic concentration and co-occurring ions like phosphate, silicate, natural organic matter (NOM), bicarbonate, sulphate, nitrate and chloride but the causal action is not well understood. Thus experiments were designed and carried out to observe these effects and get a better understanding of ECFe. The results indicate that the oxidation of Fe(II) generated during ECFe is essential for high efficiency (with respect to iron dose) of arsenic removal. Lower current intensities and pH7 were found to be most efficient for arsenic removal per unit weight of iron dissolved. Observations indicate that arsenic reacts with ferric (hydr)oxides and phosphate complexes with Fe(II). With time these complexes and precipitates are reordered to give a much higher affinity of iron (hydr)oxides for phosphate. Silicate, upto 20 mg/L, had negligible effect but at 30 mg/L was seen to reduce arsenic removal by ECFe. Increasing NOM concentrations also reduced arsenic removal but bicarbonate, sulphate, nitrate and chloride had no effect on arsenic removal by ECFe. Presence of old ferric (hydr)oxides in the reactor led to lesser requirement of Fe(II) to achieve less than 10 ppb concentration as it promoted interfacial reactions. Formation of FeAsO4 was observed by FTIR analysis of the precipitates.

Evaluation of the effect of size reduction and thermal treatment on metal extraction from PCBs of mother board and digital video drive of desktop PCs(Current Science) (V. M. Shinde
,,,,Year : 2016)
|
The study aims at evaluating the effect of particle size and thermal treatment on printed circuit boards (PCBs) of Mother Board (MB) and DVD on metal extraction. Results show around 90-95% (w/w) and 35-40% (w/w) of total Al and Cu respectively, in CPU could be recovered by systematized disassembly. Re-maining embedded Al and Cu require metallurgical or hydro-metallurgical processing. Cu extraction in-creases with size reduction. Thermal treatment of MB-PCB shows reduction in Cu extraction (23-38%) for all sizes in comparison without thermal treatment, while DVD-PCB showed surge in extraction after thermal treatment (41-141%) in comparison without thermal treatment.
