Removal of COD, colour and heavy metal from wastewater using electro–chemical technique
The effects of applied electric charge (0–200 Amp–min) and pH on the removal of colour and COD from textile wastewater have been analysed. Mild steel plates have been used as electrodes in both parallel and series connections. For colour and COD removal, four electrodes each with a surface area of 177.3 cm² and with inter–electrode distance of 2.3 cm in parallel connection ...

Comparative evaluation of EDTA, pyridine and acetic acid for the assessment of available heavy metals from domestic and industrial sludges
Various sludge samples from different domestic and industrial wastewater treatment plants were analyzed by Flame Atomic Absorption Spectrometry (FAAS) to evaluate their total and available contents of heavy metals (Pb, Hg, Cd and Zn). The EDTA, pyridine and acetic acid single extraction techniques were applied to these samples with the objective of studying the leaching behavior of the metals in ...

Ecotoxicity comparison of organic contaminants and heavy metals using
Vibrio-qinghaiensis sp.-Q67By using the Vibrio-qinghaiensis sp.-Q67 test, the concentration-inhibition relationships were established for comparing the ecotoxicity of selected organic compounds and heavy metals. The toxicity indices for the four organic compounds were 11–628 mg/L in terms of EC50,TOC (EC: effective concentration, TOC: total organic carbon), with the toxicity in an order of linear alkylbenzene ...
