摘要
提出用８０３１单片机控制的一种小型自动报警系统的设计方案，叙述了该系统的主要功能、设计原理及硬件组成、软件结构．该系统具有体积小、抗干扰能力强、造价低等特点．
The optimum condition for spectrophotometric determination of pt(Ⅳ) with 2 (3,5 dichloro 2 pyridylazo) 5 dimethylamino aminobenzene(3,5 dicl PADMA ) has been studied. In the medium of HAc NaAc buffer solution(pH=3.25～5.25),Pt(Ⅳ) can react with 3,5 dicl PADMA to form a stable blue chelate by heating in boiling wate bath. The chelate can be changed into another stable green blue species with high apparent molar absorptivity of 1 04×10 5 L·mol -1 ·cm -1 at 634 nm by addition of EtOH and mineral acid. Beer′s law is obeyed in the range of 0～12 μg/10 mL for Pt(Ⅳ) .Most common ions don′t interfere with the determination results of Pt(Ⅳ) with the masking reagent of EDTA. The method is sensitive and simple and it has been applied to the determination of trace Pt(Ⅳ) in catalysts with satisfactory results.
