| 1 | Equilibrium and kinetics of copper ions removal from wastewater by ion exchange显示文摘The removal of copper ions from wastewater by ion exchange has been studied using an iminodiacetate resin.The capacity of the resin for the copper ions has been determined to be 2.30 mmol·g^(-1) by measuring the equilibrium isotherm at 25 °C and initial pH value of 3.5 where the final equilibrium p H value is 5. An analysis of equilibrium isotherm models showed that the best fit model was the Langmuir–Freundlich. The kinetics of the ion exchange process have been investigated and four kinetic models have been tested namely: Ritchie model, pseudo-second order model, pseudo-first order model and the Elovich model. The pseudo-second order model provides the best fit to the kinetic data. | P.C.C.Siu L.F.Koong J.Saleem J.Barford G.McKay | 2016 | Chinese Journal of Chemical Engineering2016，24，1： | 9 |
| 2 | 竹制活性炭处理酸性染料废水吸附等温线模型的误差分析(英文)显示文摘High surface area activated carbons were produced by thermal activation of waste bamboo scaffolding with phosphoric acid.Single component equilibrium dye adsorption was conducted on the carbons produced and compared with a commercially available carbon.Two acid dyes with different molecular sizes,namely Acid Yellow 117(AY117) and Acid Blue 25(AB25),were used to evaluate the adsorption capacity of the produced carbons.It was found that the dye with smaller molecular size,AB 25,was readily adsorbed onto the produced carbon,nearly three times higher than a commercially available carbon,while the larger size dye,AY117,showed little adsorption.The experimental data were analyzed using isotherm equations including Langmuir,Freundlich,Tempkin,Toth,Redlich-Peterson and Sips equations.The equilibrium data were then analyzed using five different non-linear error analysis methods. | L.S.Chan W.H.Cheung S.J.Allen G.McKay | 2012 | Chinese Journal of Chemical Engineering2012，20，3： | 2 |

| 6 | 用锥形分层活性炭柱吸附去除对氯苯酚(英文)显示文摘The feasibility of adsorptive removal of single component organic compound(para-chlorophenol) by Calgon Filtrasorb 400(F400) carbon was investigated.The Redlich-Peterson equation was found to be the best fit model for describing the equilibrium relationship between the para-chlorophenol adsorption onto F400 carbon.Four adsorption columns with different column geometry and adsorbent particle stratification were used to examine the adsorption kinetics onto F400 carbons.The Bed Depth Service Time(BDST) model was applied and modified to analyse the performance of the columns and the effect of different operating variables.When combining the effects of adsorption efficiency and the associated pressure drop of each type of adsorption columns tested,the carbon stratified tapered column has been determined to be the most efficient engineering option for removing organics,in which the enhancement of the adsorbent bed in terms of longer breakthrough time and higher saturation percentage is the greatest amongst the four types of columns with reasonably small pressure drop across the fixed-bed column. | M.F.F.Sze G.McKay | 2012 | Chinese Journal of Chemical Engineering2012，20，3： | 0 |
| 7 | 废轮胎二氧化碳活化借助析因设计的系统分析(英文)显示文摘In this study,waste tire was used as raw material for the production of activated carbons through pyrolysis.Tire char was first produced by carbonization at 550℃ under nitrogen.A two factorial design was used to optimize the production of activated carbon from tire char.The effects of several factors controlling the activation process,such as temperature(850-950 ℃),time(2-6 h) and percentage of carbon dioxide(70%-100%) were investigated.The production was described mathematically as a function of these three factors.First order modeling equations were developed for surface area,yield and mesopore volume.It was concluded that the yield,BET surface area and mesopore volume of activated carbon were most sensitive to activation temperature and time while percentage of carbon dioxide in the activation gas was a less significant factor. | P.P.M.Fung W.H.Cheung G.McKay | 2012 | Chinese Journal of Chemical Engineering2012，20，3： | 0 |
| 8 | 由竹脚手架制备的活性炭经化学修饰后的表征(英文)显示文摘In this study,bamboo scaffolding was used to produce activated carbon by carbonization at 600 ℃ and 900 ℃ with the purge of nitrogen.The 600 ℃ char was then further modified chemically by acids and alkalis by reflux for 6 hours.The produced chars were then characterized by nitrogen adsorption isotherm,He pyncometry,pH,elemental analysis and Boehm titration.For most of the chemically modified carbons,the micropore surface areas and volumes have increased compared with the 600 ℃ char,while the mesopore surface areas and volumes slightly decreased,which may have been due to the dissolving of some of the permeated inorganic matter and oxidizing deposited carbon that blocks the pore openings.For the acidic modified carbons,larger amounts of acidic groups were present in the carbons after being activated by phosphoric acid,phosphoric acid further treated with 2 mol·L-1 nitric acid,and calcium hydroxide.Although carbon treated with 2 mol·L-1 and 5 mol·L-1 nitric acid also produced high acidity,the surface areas and pore volumes were relatively low,due to the destruction of pores by nitric acid oxidation.The reduction of porosity may impair the adsorption capacity. | W.H.Cheung S.S.Y.Lau S.Y.Leung A.W.M.Ip G.McKay | 2012 | Chinese Journal of Chemical Engineering2012，20，3： | 0 |
