自动电位滴定仪测定海洋沉积物中碳酸盐百分含量
THE DETERMINATION OF CARBONATE CONTENT IN MARINE SEDIMENTS BY AUTOMATIC POTENTIOMETRIC TITRATOR
摘要
Abstract
Based on the volumetric method, the determination of carbonate content in marine sediment was carried out by automatic potentiometric titrator with related software-tiamo, which can export the results automatically. This method is simple and rapid for batch measurement. The results were consistent with standards defined by the National Standard Reference of Deep-Sea Sediment. Seven independent determinations were measured for the same sample, and the standard deviation of the results was less than 0. 9 %. Several samples of sediment core MD06-3050 were used to measure carbonate content by automatic potentiometric titrator and ICP-OES. The results of two methods were consistent.关键词
