15 صفحه اولAdsorption of heavy metals using marine algae
The discharge of heavy metals into aquatic ecosystem has become a matter of concern in South Africa over the last few decades. These pollutants are introduced into the aquatic systems significantly as a result of various industrial operations. Conventional methods for metal removal such as ion exchange, reverse osmosis, etc. have proven to be expensive. Due to the increasing awareness of ecolog...
متن کاملCompetitive adsorption of dyes and heavy metals on zeolitic structures.
The adsorption of Acid blue 25, basic blue 9, basic violet 3, Pb(2+), Ni(2+), Zn(2+) and Cd(2+) ions has been studied in single and dye-metal binary solutions using two mineral materials: Clinoptilolite (CL) and ER (Erionite). These zeolites were characterized by FT-IR spectroscopy; potentiometric titration and nitrogen adsorption isotherms at 77 K to obtain their textural parameters. Results i...
متن کاملAdsorption and toxicity of heavy metals on activated sludge
The adsorption of Cu, Cd, Ni, Zn, and Cr from synthetic solutions on powdered activated carbon (PAC), activated sludge, and dried sludge were investigated under laboratory conditions to assess its ability to remove heavy metals. The adsorption efficiency increased rapidly within the first 30 min and then slowed down as it approached a steady state after 5 h of contact time. The results showed t...
متن کاملTorularhodin Biosynthesis and Extraction by Yeast Cells of Rhodotorula Rubra
The paper presents the research work done to study the discontinuous bioprocess for the intracellular carotenoidic pigment torularhodin formation with the yeast Rhodotorula rubra ICCF 209. The growth and carotenoid biosynthesis of the yeast Rhodotorula rubra was studied by cultivation in 3.7 L Bioengineering AG lab bioreactor with mechanical stirring at an air flow rate of 200 L/h and agitation...
