摘要采用吸附溶出伏安法（AdSV）测定压力分解后的石英和硅玻璃样品中的钛和铁。用扁桃酸和儿茶酚分别作为钛和铁的络合剂。该方法是利用氯酸盐离子的催化作用测定钛的。用能量色散x射线分析了石英和硅玻璃样品在HF+H2SO4混合物中分解后的不溶性残留物。ET-AAS作为AdSV测量的参考方法。
Abstract Adsorptive stripping voltammetric (AdSV) methods are presented for the determination of titanium and iron in quartz and silica glass samples obtained after pressure decomposition. Mandelic acid and catechol were used as complexing agents for titanium and iron, respectively. The method for titanium determination is based on the catalytic effect of chlorate ions. An insoluble residue remaining after decomposition of quartz and silica glass samples in HF+H2SO4 mixture was checked by energy-dispersive X-ray analyses. ET-AAS was applied as a reference method to AdSV measurements.
