【摘要】 为了更好地了解尿素中和法制备云母钛珠光颜料过程中钛水解的机理,指导高档次云母钛珠光颜料的制备,需要对该过程中钛的含量进行准确快速的测定,本文对过氧化氢分光光度法测定钛的方法进行了实验研究.得出钛离子含量的线性范围(0~3mg)/100mL,回归方程为:=7.75831E-4+0.28384(mg/100mL),相关系数=0.9994,摩尔吸光系数=755.7L/(molcm).更多还原

【Abstract】 For thesake of knowing mechanism of preparing nacreouspigment of mica titanium and adjusting pH with urea, we need to measure fast and exactly concentration of titanium to direct preparing top grade nacreous pigment of mica titanium. The author researches the method of hydrogen peroxide spectrophotometry to measure concentration of titanium, and elicitthe conclusion that linearityrangeoftitanium content is (0 ~ 3mg ) /100 mL, regressive equationis = 7.758 31E 4 + 0.283 84 (mg/100 mL), the correlation coefficient is = 0.999 4, and the molar absorptivity is = 755.7 L/ (mol cm).更多还原
