有的资料提出在草酸钠饱和的1 N 硫酸底液中进行钢铁中钛量的阴极波示波极谱测定,又有资料提出利用草酸钠饱和并含有8%尿素的1N 硫酸溶液抑制电流峰进行土壤中钛的测定。而钛的这种络合物,其半波电位并不随钛及铁的浓度变化而变更。在此基础上,我们在示波极谱仪器上发现钛的阴极波形与线性关系较差,且受样品中铜与氧的干扰严重。但是我们找到在约-0.2伏电位处,钛产生有一良好的阳极波形,且无上
Some data suggest that cathodic oscillopolarographic determination of the amount of titanium in steel is carried out in a sodium oxalate saturated 1 N sulfuric acid bottom solution and there is also information suggesting that the use of a 1 N sulfuric acid solution saturated with sodium oxalate and containing 8% Determination of titanium in soil. This titanium complex, its half-wave potential does not change with the concentration of titanium and iron change. On this basis, we found on the oscillographic polarographic instrument titanium cathode waveform and linearity is poor, and by the sample of copper and oxygen interference serious. However, we find that at about -0.2 volts, titanium produces a good anode waveform,
