Abstract
08Jun 2017 REMOVAL OF CARCINOGENIC HEXAVALENT CHROMIUM FROM CONTAMINATED WATER USING ACTIVATED CARBON DERIVED FROM BOMBAX CEIBA BARK. Rahangdale P. K , Donadkar D. K and Gour K. Bhawabhuti College, Amgoan-441902, India. Priyadarshini College of Engineering, Nagpur-440019, India. Priyadarshini J. L. College of Engineering, Nagpur-440009, India.
Highlights
Environmental pollution is currently one of the most important issues facing humanity
It can be seen that Cr(VI) ion removal efficiency of activated carbon derived from the bark of Bombax ceiba(ACBCB) was greater in the initial stages gradually increased upto 97.8% and remains almost constant, after optimum period of 110 min

Summary
Environmental pollution is currently one of the most important issues facing humanity It was increased exponentially in the past few years and reached alarming levels in terms of its effects on living creatures. Out of the various toxic heavy metal pollutants chromium and its compounds are considered as the most dangerous inorganic water pollutants. Chromium is a chemical element which is derived from the Greek word "chroma" meaning colour, because many of its compounds are coloured. It is the first element in group 6 having atomic number 24 and symbol Cr. Chromium is a hard metal that has high melting point and it is colorless, tasteless and malleable. Chromium compounds present in the effluents as a result of electroplating, metal finishing, magnetic tapes, wood preservation, leather tanning, pigments and chemical
