Adsorption of chromium (VI) from aqueous solution using various low-cost adsorbents: a comparative study

When present as a pollutant in water, the hexavalent chromium compounds are carcinogenic, corrosive on tissue, and toxic to bacteria, plant, animals and people even at low concentrations. This chapter presents an investigation of adsorption efficiency of coconut husk, sugarcane pulp residue, and pow...
