Analytical Equipment一、www.lumexinstruments.com series DETERMINATION OF WATER-SOLUBLE FORMS OF INORGANICAND ORGANIC ANIONS IN SOILS，CLAYS，PEATS， WASTEWATER SILTS， ACTIVATED SLUDGES， AND BOTTOM SEDIMENTS Lumex Method M 03-06 (2010) INTRODUCTION The method allows determination of water-soluble forms of inorganic (chlorides， sulfates， nitrates， fluorides，and phosphates) and organic (acetates， formates， and oxalates) anions in soils， clays， peats， wastewatersilts， activated sludges， and bottom sediments by capillary electrophoresis method. MEASUREMENTMETHOD The measurement method is based on the extraction of water-soluble forms of inorganic anions by distilledwater from a soil sample to the 1：5 ratio and subsequent separation， identification， and determination ofanalyzed components by the capillary electrophoresis method with indirect anion detection at wavelengths of254 nm or 374 nm. MEASUREMENT RANGE The measurable anion weight fraction ranges are listed below. Anions Measurement ranges*， mg/kg Anions Measurement ranges*，mg/kg Acetate 3.0-1000 Formate 1.0-500 Nitrate 3.0-10000 Phosphate 3.0-5000 Oxalate 3.0-100 Fluoride 1.0-100 Sulfate 3.0-20000 Chloride 3.0-20000 *- For the sample/distilled water weight ratio 1：5. Other inorganic and organic anions do not interfere with determination of the analyzed anions. 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/7/8operating system with installed dedicated software package ELFORUN. All reagents must be of analyticalgrade or better.
