In this improved method for quantifying 3-methoxy-4-hydroxyphenylethyleneglycol (MHPG) in urine, after a multistep extraction of MHPG and internal standard (iso-MHPG) from 3.0 mL of urine, the compounds are separated on a C18 reversed-phase column and quantified by use of an electro-chemical detector. The isocratic chromatographic separation takes about 16 min. The mobile phase is phosphate buf...

Wastewater treatment is gaining importance because of increasing awareness about health effects of water pollutants and stringent norms of regulatory bodies. Removal of heavy metals from industrial effluent can be carried out by various methods like ion exchange, adsorption, activated sludge process, electro coagulation, membrane separation processes, precipitation, coagulation etc. Arsenic is ...
