天然水、饮用水和废水样品中醋酸阴离子检测方案(毛细管电泳仪)

w重Analytical EquipmentHIGH PERFORMANCECAPILLARY ELECTROPHORESISSYSTEM2一w一 DETERMINATION OF ACETIC ACID (ACETATE ANIONS)IN NATURAL， DRINKING， AND WASTE WATER Lumex Method M 01-49-2011 INTRODUCTION The method is used for the determination of acetic acid (as acetate ions) in the samples of natural water，drinking water， and waste water by capillary electrophoresis. MEASUREMENTMETHOD The method is based on the sample filtration and dilution and its subsequent analysis by capillaryelectrophoresis with indirect anions detection at 266 nm. MEASUREMENT RANGE Measurement range of the acetic acid (acetate anions) in the samples is 0.01-10000 mg/L. The upper bound of the measurement range is indicated allowing for the dilution. Carbonates and other inorganic anions at concentrations characteristic for these sample types do nothamper determination of the acetic acid within the 0.1-10000 mg/L range. For the analyses of samples withlow acetic acid content (lower than 0.1 mg/L) the total content of basic inorganic anions (chlorides， sulfates，and carbonates) in the sample should not be higher than 300 mg/L. EQUIPMENT AND REAGENTS The CAPEL capillary electrophoresis system is used in measurements. Data acquisition， collection，processing and output are performed using a personal computer running under WINDOWSXP/7/8/10operating system with installed dedicated software package ELFORUN. All reagents must be of analyticalgrade or better. EXAMPLE OF A REAL ANALYSIS BGE： PABA， with DEA and CTA-OH The contents on this paper are subject to change without notice.
