碘量法测定铜早在1854年就有人首先提出,至今已有一百多年的历史。由于消除干扰的手段不同又分为硫代硫酸钠法,氨法,碘氟法,氟化氢钠——六偏磷酸钠法,六偏磷酸钠法等。其中前二种方法由于硫程较长,在大批生产中较少采用。碘氟法具有准确度高速度快,适于大批生产等优点为目前国内大多数化验室所采用。 Iodometric determination of copper as early as 1854 was first proposed, so far, a hundred years of history. As a means of eliminating interference is divided into sodium thiosulfate method, ammonia method, iodine fluoride method, sodium bifluoride - sodium hexametaphosphate method, sodium hexametaphosphate method. The first two methods due to the longer sulfur, less used in a large number of production. Iodine fluoride method with high accuracy and speed, suitable for mass production advantages for the majority of domestic laboratories used.
