“…concentration approach 200-500 mg/L in the industrial wastewaters. This value is very high in relation to the water quality standards and it should be reduced to a range of 0.1-0.05 mg/L (Ucun et al 2003;Vilar et al 2005;Ö zaçar et al 2008).…”

“…2) can be used to assess the dependency of the process on the sorbed Pb(II) or Ni(II). where k 2 is the overall rate constant for the adsorption process [dm 3 (mg min -1 )], q e is the amount of metal ion adsorbed at equilibrium (mg g -1 ) and q t is the amount of metal ion adsorbed at any time t (mg g -1 ). Re-arrangement of equation (2) The initial sorption rate, h , as t → 0 can be defined as in equation (4) .…”

“…Heavy metals such as lead and nickel are but two of the species of particular concern environmentally and are discharged to the environment in the wastewaters associated with industries such as mineral processing, non-ferrous metal porcelain enamelling, electroplating, copper sulphate manufacture, ammunitions and battery manufacture [2]. Discharge concentrations for both Pb(II) and Ni(II) can range from 3.4 to 900 mg dm -3 [3]. Pb(II) accumulates in vital organs and bones and causes a number of diseases ranging from anaemia to nervous system degeneration [4].…”

“…These materials including sugarcane bagasse, risk husk, tea leaves, bamboo dust, maize cob, tree sawdust [3], zeolite [4,5], bentonite [6,7], montmorillonite [8], Cephalosporium aphidicola [9], Pinus sylvestris [10], Saccharomyces cerevisiae [11], and so forth. Despite the mentioned materials, Ficus religiosa leaf powder can also be utilized as adsorbents to remove heavy metals from aqueous solution [12,13,14,15,16,17].…”
