BIOSORPTION OF PRECIOUS AND HEAVY METALS* [PDF]
, 2002 The biosorption of metals has already attracted a great deal of attention because of its application potential in environment protection and removal or recovery of precious and heavy metals. The research activities about biosorption of precious and heavy

Freshwater green macroalgae as a biosorbent of Cr(III) ions
Open Chemistry, 2018 The research was conducted to evaluate the possibility of using algae enriched with Cr(III) ions as a feed additive for horses. As a sorbent, macroalga Cladophora glomerata was chosen. The results of the kinetic and equilibrium experiments on biosorption

Toxic metal removal by Biosorption
, 2019 Toxicity of Flouride and Chromate ions is well known,causing Fluorosis and Cancer respectively. Arsenic , mercury, lead and cadmium are highly toxic even at low levels. Zn( ll) is substituted in metallo enzymes by cadmium. Toxic As ( lll) inhibits enzyme action. Mercury is responsible for Minimata disease while lead poisoning occurs due to its presence
