(2015-05-18)İn this study, glass and carbon fibres reinforced composite materials have been produced with eight laminates. For experimental study, specimens with 10 mm internal hole were prepared. Then, these specimens have been ...
-
(2014-11)In this study, the relationship between surface roughness of workpiece and process parameters and was investigated for AA7075 aluminum alloy with electrical discharge machining (EDM). Experiments were conducted under ...
-
(1998)The adsorption ability of activated carbons from sugar beet pulp to remove the cadmium from aqueous solutions has been investigated. Optimum temperature and time for carbonization of sugar beet pulp were determined as 700 ...
-
(1999)This study deals with the removal of Cr(VI) from aqueous solutions by using filter cake known as zinc extraction residue (ZER) generated as a by product in a zinc production plant located in Kayseri-TURKEY. It was found ...
-
(1999)The ability of Copper Smelter Slag (CSS) to reduce Cr(VI) in aqueous solutions has been investigated. The extent of reduction is dependent on the amounts of acid and reductant, contact time, Cr(VI) concentration, temperature ...
-
(2000)Use of red mud, which is a waste product from bauxite processing, has been explored as an alternate adsorbent for arsenic in this study. The tests showed that the alkaline aqueous medium (pH 9.5) favored the removal of ...
-
(2001)This study was carried out to reduce Cr(VI) in aqueous solutions by using synthetic iron sulphide. For that purpose, the effects of acid content, contact time, initial Cr(VI) concentration, temperature of the solution, ...
-
(1990)Sulphation roasting of primary and secondary copper slags has been carried out to facilitate the dissolution of copper, nickel, cobalt, zinc and iron. The process comprised preroasting of the ground slag followed by ...
-
(1997)The reduction of Cr(VI) by steel wool and the precipitation of reduced chromium by CaCO(3) powder and NaOH solution were investigated in continuous and batch systems, respectively. The effects of acid and initial Cr(VI) ...
-
(2003)The adsorption of Cd(II) ions from aqueous solutions onto activated carbon obtained by carbonising sugar beet pulp impregnated with 30% phosphoric acid was studied. By increasing the temperature of carbonisation, the removal ...
-
(2004)In this article, dissolution characteristics of Cr(VI) reduction–precipitation sludges in the solutions containing mineral acids, organic complexing materials or both are examined. For this purpose, the effects of pH, ...
-
(2004)In this study, extraction characteristics of Cu, Co, Zn and Fe from copper converter slag by oxidative leaching with potassium dichromate–sulphuric acid lixiviant were investigated. The experimental results indicated that ...
-
(2004)This research summarises the results of the study on the removal of chromium by applying the ferrite process to the solutions obtained from two different Cr(VI) reduction processes utilising sodium sulphite and ferrous ...
-
(2004)Hexavalent chromium is a common and toxic pollutant in soils and wastewaters. Reduction of the mobile Cr(VI) to less mobile and less toxic Cr(III) is a solution for decontamination of industrial effluents. In this study, ...
-
(2004)Zinc and lead recovery from zinc plant residue (ZPR) has been investigated. The residue is discarded as a cake from a Waelz kiln processing zinc–lead carbonate ores. The zinc plant residue containing 11.3% Zn, 24.6% Pb, ...
-
(2012)This article describes the use of citric acid modified sugar beet pulp as new ion-exchanger sorbent for the removal of metal cations and colorants from thin juice. The results of batch adsorption runs concerning the effects ...
-
(2009)Sorption of Cd2+, Cr3+, Cu2+, Ni2+, Pb2+ and Zn2+ onto a carboxyl groups-rich material prepared from lemon was investigated in batch systems. The results revealed that the sorption is highly pH dependent. Sorption kinetic ...
-
(2008)A cation exchanging material was developed from lemon by modifying the pectic–cellulosic substances in the lemon peel by lemon juice having citric acid. For this purpose, chopped lemon removed from seeds and yellow skin ...
-
(2007)A carbon rich adsorbent prepared from the reaction of sugar beet pulp with sulphuric acid and gas formed during carbonization process have been studied for Cr(VI) removal from aqueous solutions. The SO2 rich gas was shown ...
-
(2006)In this study, the effects of some parameters on the extraction of metals from copper converter slag by using a sulphuric acid/potassium dichromate lixiviant were investigated. The leaching kinetic of copper from converter ...
