Net consequence of the coupling of alternating absorbent fluid position displacements with cycling of a thermodynamic intensive parametric variable (temperature) is a buildup of separation from cycle to cycle. Direct mode of thermal PP was used to separate Cr (VI) from wastewater using low cost adsorbent sawdust carbon. Removal of Cr (VI) decreases as initial concentration increases. For same number of cycles, separation factor increases as upper half cycle temperature increases for same initial concentration of feed. There is an increase in adsorption with increasing pH. A marked increase in separation can be achieved using thermal PP in place of adsorption. <br/> <br/>Page(s): 79-84 Fri, 29 Dec 2006 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/1113 Title: Batch washing of heavy metals from municipal solid waste (MSW) compost using Na₂EDTA and a mixture of Na₂S₂O₅ and Na₂EDTA <br/> <br/>Authors: Ozbas, Emine Elmaslar; Bayat, Cuma; Balkaya, Nilgun <br/> <br/>Abstract: Main factor leading to restricted soil conditioner use of compost is its heavy metal content. This paper deals with the removal of heavy metals from municipal solid waste (MSW) compost using Na₂EDTA and a mixture of Na₂S₂O₅ and Na₂EDTA in the batch mode. At the end of extraction studies, for 3 h at 1:25 solid:liquid ratio by using 0.05 M Na₂EDTA, 100% removal yields were obtained for all metals studied. Further, heavy metal removal ( 100%) were obtained with 0.01 M Na₂EDTA and 0.1 M Na₂S₂O₅, at 1:6 solid:liquid ratio, for all heavy metals of this study. <br/> <br/>Page(s): 75-78 Fri, 29 Dec 2006 22:58:59 GMT http://nopr.niscair.res.in/handle/123456789/1112 Title: Froth flotation pretreatment for enhancing desulfurization of coal with sodium hydroxide <br/> <br/>Authors: Saydut, Abdurrahman; Tonbul, Yalcin; Baysal, Akin; Duz, M Zahir; Hamamci, Candan <br/> <br/>Abstract: Froth flotation (FF) pretreatment of coal from Hazro, Turkey, for enhancing desulfurization with sodium hydroxide was investigated. FF reduced following contents of coal: ash, 58.54; pyritic sulfur, 79.34; and volatile matter, 56.98%. The coal flotation was 69.59%. FF could not remove organic sulfur. Coal concentration obtained from flotation was leached using aqueous NaOH and its organic sulfur content was reduced by 59.27%. Hence using combination of two methods, total sulfur, ash and volatile matter contents was reduced by 88.06%, 63.13% and 77.32%, respectively. <br/> <br/>Page(s): 72-74 Fri, 29 Dec 2006 22:58:59 GMT
