Removal of copper from aqueous solutions by phosphate rock

Lead Inhibition on Urea Hydrolyzing Microorganisms Under Batch Conditions

“…Heavy metals such as copper, zinc, lead, mercury, chromium, cadmium, iron, nickel and cobalt are main toxic pollutants in industrial wastewaters (24). Various industrial sectors generate effluents containing high levels of heavy metals.…”

Equilibrium and Kinetic Parameters Determination of Cr(VI) Adsorption by Hogla Leaves (Typha elephantina Roxb.)

“…Natural materials which are available in large quantities or certain waste products from industries or agriculture have drawn attentions to researchers to be used as inexpensive adsorbents. Some of these are tea factory waste [4], eucalyptus bark [5], Hevea brasilinesis sawdust [6], beech sawdust [7], the agricultural byproduct of Lentinus edodes [8], non-living microbial biomass [9], fresh water algae [10], clay mineral [11], phosphate rock [12], etc. Among these adsorbents the ability of biological materials to adsorb metal ions has drawn considerable attention for the development of an efficient, clean and cheap technology for wastewater treatment [4].…”

Kinetic, isotherm and thermodynamics investigation on adsorption of divalent copper using agro-waste biomaterials, Musa acuminata, Casuarina equisetifolia L. and Sorghum bicolor

“…3). An increase in contact period between adsorbent and Cu(II) ions increases the adsorption of metal ion as because more time familiarizes the metal ion to bond with the adsorbent 25, 26 . The results revealed that the equilibrium was established at a point of 180 min in case of BSP and 120 min in case of SSP and CFP as adsorbents.…”
