2010,Vol.27No.10 Chemistry&Bioengineering:武汉市科技计划项目(200860423202):2010-09-10:万昆(1967-),男,湖北武汉人,实验师,主要从事化学工艺研究;通讯作者:李忠铭,教授。E-mail:lzm-zrx@163.com。 ,, ,,(江汉大学化学与环境工程学院,湖北武汉430056)   :分别采用DDS-Ⅱ型电导仪和3700E型感应式电导仪对HCl/H2SO4/NaOH标准溶液的电导值进行了测定,并探讨了温度、浓度以及杂质含量对电导值的影响。结果表明,相比于DDS-Ⅱ型电导仪,3700E型感应式电导仪可以更好地用于纺织整理废水中酸碱的在线检测,并根据温度、浓度与电导值之间的关系建立了适用于一定温度和浓度的电导数学模型,进一步提出纺织整理废水中杂质的影响不容忽略。:纺织整理废水;3700E型感应式电导仪;温度;浓度;电导值:TQ085.4 O646.1    :A    :1672-5425(2010)10-0047-03  、,,,“”[1,2]。,[3~6]。3700E(0.065~0.125mol·L-1、0.100~0.200mol·L-1、NaOH0.070~0.180mol·L-1),、,。1 1.1 ,,;,,;NaOH,,。DDS-Ⅱ、FC204,;3700E,;CS501,。1.2 、、NaOH0.065~0.125mol·L-1、0.100~0.200mol·L-1、0.070~0.180mol·L-1。1.3 DDS-Ⅱ、3700EHCl/H2SO4/NaOH,,。,3700E、HCl/H2SO4/NaOH,、。,3700EHCl/H2SO4/NaOHHCl/H2SO4/NaOH,。2 2.1 (1)1,HCl/H2SO4/NaOH,;,DDS-Ⅱ3700E。3700E106mS·cm-1,,DDS-Ⅱ[7,8]。,3700E。2.2 、3700EHCl/H2SO4/NaOH,2。2,HCl/H2SO4/NaOH,,;47 :/201010,HCl/H2SO4/NaOH,。HCl、H2SO4NaOH,,,[9]。,32℃HCl/H2SO460℃NaOH,HCl/H2SO4/NaOH,,1。1  HCl/H2SO4/NaOH、Tab.1 Mathematicalmodelforconcentration,temperatureandconductivityvaluesinHCl/H2SO4/NaOHstandardsolutions /mol·L-1  /℃ HClD=0.71169+42.34598c+0.0389×(T-32)0.063~0.12032~85H2SO4D=1.15423+42.08809c+0.04162×(T-32)0.115~0.15032~90NaOHD=0.69655+34.6252c+0.065×(T-60)0.11~0.1832~90:D;c;T2.3 ,3700EHCl/H2SO4/NaOHHCl/H2SO4/NaOH,,2。2,HClHCl,H2SO4NaOH,NaOH,31.8%。,[10~12],、HCl、H2SO4、NaOH,HClHCl,H2SO4NaOH。,。3 (1)DDS-Ⅱ,3700E。48 :/2010102  Tab.2 Theconductivityvaluesatdifferenttemperatures/℃/S·m-1HCl    /%H2SO4    /%NaOH    /%322.652.888.75.254.995.03.052.0831.8402.883.1810.45.585.216.63.212.4523.7503.183.406.95.905.555.93.782.9023.3603.423.7810.56.185.806.24.193.3021.2703.654.0511.06.505.988.04.653.7020.4803.904.5015.46.786.257.85.024.4212.0904.01(85℃)4.62(85℃)15.27.056.507.85.584.9810.8  (2)HCl/H2SO4/NaOH、,。(3)HCl/H2SO4/NaOHHCl/H2SO4/NaOH,。:[1] ,.[J].,2006,(2):24-27.[2] ,.[J].,2003,(6):132-136.[3] ,,,.[J].,2008,(20):5-6.[4] ,.[J].(),1996,2(2):23-28.[5] ,.-[J].,2007,7(17):4438-4440.[6] ,,.[J].,1999,19(3):164-167.[7] ,,.[J].,2001,15(2):117-118,122.[8] .[J].,2006,(1):45.[9] ,.()[M].:,2003:74-83.[10] ,.[J].,2003,(1):30-31.[11] ,,.[J].,2003,22(3):9-11.[12] ,,,.[J].,2009,22(1):36-37,40.StudyonEffectFactorsofConductivityValuefortheTextileFinishingWastewaterWANKun,ZHOURui-xue,WANGFei,CHENFeng-juan,LIZhong-ming(CollegeofChemical&EnvironmentalEngineering,JianghanUniversity,Wuhan430056,China)Abstract:TheconductivityvaluesofHCl/H2SO4/NaOHstandardsolutionweremeasuredbyDDS-Ⅱcon-ductivitymeterand3700Einductiveconductivitymeter.Itwasalsoinvestigatedthattheinfluencesoftempera-ture,concentrationandimpuritiesontheconductivityvaluesoftheHCl/H2SO4/NaOHstandardsolutionby3700Einductiveconductivitymeter.TheexperimentalresultsshowedthatcomparedwithDDS-Ⅱconductivitymeter,3700Einductiveconductivitymeterwasthefavorableinstrumentformeasuringtheconductivityvalueofthetextilefinishingwastewateronline.Inaddition,theconductivitymathematicalmodel,whichwasrelatedtothetemperatureandtheconcentrationofthesolution,wasestablishedandappliedtoacertaintemperatureandacertainconcentration.Itwasalsoindicatedthattheimpuritieshadaneffectontheconductivityvalueofthetextilefinishingwastewater.Keywords:textilefinishingwastewater;3700Einductiveconductivitymeter;temperature;concentration;conductivityvalue49
