电导法离子浓度检测电导法离子浓度检测measurement of ion concentration by conductivity method  d londoofo}}21 nongdu JI0nee电导法离子浓度检测(measurement of ioneoneentration by eonduetivity method)根据两电极间电解质的电阻测定溶液离子浓度的检测技术。常用仪器为电导式离子浓度计。在电解质溶液中,插入面积为A、间距为L的两个电极,其间溶液的电导G可表示为‘一SA/L或S~GL/A~KR。式中R为两极板间溶液的电阻,它等于电导的倒数;S为溶液的电导率,S/m;K二L/A称为电导池常数。电解质在水中电离成正负离子,形成溶液中离子的迁移导电,其电导与浓度C的关系为 占K__。 〔一二~月云火10。 入R‘、一式中占为每摩尔电解质的克数;入,为溶液的当量电导。测量溶液的电阻值,便可得到被测溶液中电解质的浓度C。根据这个原理设计了多种型式的电导分析仪。在稀溶液中,电解质的浓度与电导有着线性关系;随着浓度的增加,离子间力的作用加大,电导一浓度曲线出现了极值和非线性的复杂关系。通常电导分析法只适用于电导一浓度关系曲线呈线性和近似线性范围的单一电解质溶液。电导式离子浓度计结构简单,价格低,维护方便,应用广泛。它分为电极式和电磁感应式两类。 电极式电导仪有两极式和四极式两种。典型的两极式电导仪是将固定在玻璃管或环上的两片镀铂黑电极(或铂片)作为发送器,采用分压式或平衡桥式电路测量待测溶液(装在电导池内)的电导值。为避免电极极化和电解,测量电路要用高频交流电源。四极式电导仪用四个电极作为发送器,其中两个为接入电源的导流电极,其余两个为测量电极,利用测量电流在溶液电阻上的电位差得到溶液的电导值。测量电极通常接入高阻抗放大器,使测量电极无电流通过,从而避免了电极极化,减少了因电极表面污染结垢所造成的测量误差。在选矿厂,四极式电导仪可用来在线检测矿浆碱度和水玻璃离子浓度。 电磁感应式电导仪又称无电极电导仪,或电磁一电导式离子浓度计。其发送器由两个高导磁环形变压器,即励磁变压器T,和检测变压器T。组成,被测溶液D,在此是一根充满待测溶液的环管,作为励磁和检 乙参澎丢 电磁感应式电导仪原理图测变压器的祸合回路。(见图)当TI的初级绕组通以交 __.W流电时,在其次级绕组上产生的感应电压为砒一斌u:,u:为了’:初级绕组电压;Wl、W:分别为T,的初级和次级绕组匝数;于是在D回路上便产生感应电流几几一搬,此感应电流在跳的次级绕组上产生的电压u2一、黔w6,式中‘为比例系数,ws一w6,W,己知,于是测出u:便可测知溶液的等效电阻R。,或电导1/尺。,从而得到溶液的离子浓度。电磁感应式电导仪的发送器无极化效应,并用工程塑料包封,可用于高电导率、强腐蚀性介质,适用于在线检测,(其结构有沉入式、流动式和管路式)仪器的转换器有平衡式和直读式两种。这类仪器的测量精度较高,性能较稳定。
