摘　　要：微量氯的测定至今还不能令人满意,如离子选择电极法灵敏度不高;比色法则空白值太高;比浊法也因试剂污染而引起影响。为此本法采用一特制的以哈夫炉作炉膛带有石英管的小型热解炉高温热解试样,直接以硫氰酸汞—铁盐溶液吸收被分解出来的氯,以光度法测定之.A method is suggested for spectrjphotometric determination of chlorine in ores.It is based on pyrolysis of the sample a high temperature furnace.The chlorine is absorbed in the mixture solution of mercuric thiocyanate and ammonium ferrin sulfate.
