中文摘要：
基于容量法原理,探讨了海底沉积物中碳酸盐的自动电位滴定法,配合tiamo软件,自动计算并输出测定结果。该法简单快速,且可以批量测试,经深海沉积物等国家标准物质验证,结果与标准值相符。对同一样品进行7次测定,其结果的相对标准偏差小于0.9%。该方法应用于西菲律宾海岩心MD06-3050的部分样品,测试结果与ICP-OES方法得到的结果具有一致性,该方法再现性良好,准确可信。
英文摘要：
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.
