A chelating resin, pyrocatechol violet (PV) immobilised on an Amberlite XAD-1180 support, was prepared and its use for the atomic absorption spectrometric determination of aluminium was investigated. The XAD-1180-PV resin was characterised by infrared spectrometry and thermal gravimetric analysis. The optimum pH value for quantitative sorption is 8-9, and desorption can be achieved by using 5.0-10.0ml of 2M HCl. The effects of diverse ions on the sorption and recovery of aluminium have been studied. The capacity of sorbent was 6.45+/-0.59mgg(-1) Al XAD-1180-PV. Recoveries for aluminium from water samples were in the range 95-105%. The accuracy of procedure was confirmed by aluminium determination in certified reference materials. The method developed was applied with varying results to the analysis of natural water, haemodialysis fluids and microwave digested red wine samples from Tokat City.
制备了一种固定在Amberlite XAD - 1180载体上的螯合树脂——邻苯二酚紫（PV），并研究了其在原子吸收光谱法测定铝中的应用。采用红外光谱法和热重分析法对XAD - 1180 - PV树脂进行了表征。定量吸附的最佳pH值为8 - 9，使用5.0 - 10.0ml的2M盐酸可实现解吸。研究了多种离子对铝吸附和回收率的影响。吸附剂对铝的吸附容量为6.45±0.59mg g(-1) Al XAD - 1180 - PV。水样中铝的回收率在95% - 105%之间。通过对有证标准物质中铝的测定，证实了该方法的准确性。所开发的方法应用于来自托卡特市的天然水、血液透析液和微波消解红酒样品的分析，结果各异。
