以及西田宏先后研究了非离子表面活性剂作用于Be-CAS二元体系的光度法。前者用ОП-10或ОП-7测定了三元体系的组成;后者研究了阴离子(ClO_4~-)的影响。本文确证乳化剂OP进入络合物组成,摩尔吸光系数ε=9.6×10~4,桑德尔系数S=9.4×10~(-5)微克/厘米~2,对比度Δλ=190hm。乳化剂OP进入组成使三元体系较二元体系的吸收峰红移80nm。一定量的39种阳离子和部分阴离子不干扰测定(P~s=1～5.7)。测定含镀10~(-4)～10~(-2)%的矿石试样能符合规定的质量要求。
And Nishida macro has studied the non-ionic surfactant acting on the Be-CAS binary system spectrophotometry. The former measured the composition of the ternary system with ОП-10 or ОП-7; the latter studied the effect of anions (ClO 4 -). This article confirms the emulsifier OP into the complex composition, the molar absorption coefficient ε = 9.6 × 10 ~ 4, the Sardar coefficient S = 9.4 × 10 -5 micrograms / cm ~ 2, the contrast Δλ = 190hm. Emulsifier OP into the composition of the ternary system than the binary system red shift 80nm. A certain amount of 39 kinds of cations and some anions do not interfere with the determination (P ~ s = 1 ~ 5.7). Determination of ore containing 10 ~ (-4) ~ 10 ~ (-2)% of the sample can meet the required quality requirements.
