The studies performed with the chinalizarin method the for determination of the concentration of boric compounds in the air of the working area, proved to be impracticable in the presence of geranium and beryllium compounds. A spectrometric method for analysis of boric compounds was developed, based on their interaction with fluoric and ferric ions in the presence of sulfo-salicylic acid, and a complex compound was received of light orange colour to red, depending on the boric concentration. The maximum of absorption was at wave length of 577 mm. The sensitivity of the method was 0.001 mg boric in the analyzed sample -2 cm3. There is a linear dependence between the boric concentration and the optic density of the developed samples of interval 0.001-0.15 mg borium. The accuracy of the method expressed by coefficient of variation in % is in interval 12.4-6.3% for borium concentrations of 0.001-0.1 mg. The field where the method could be applied is defined in the presence of titanium, copper and lead compounds.
用茜素法测定工作区域空气中硼化合物浓度的研究表明，在存在天竺葵和铍化合物的情况下该方法不可行。基于硼化合物在磺基水杨酸存在下与氟离子和铁离子的相互作用，开发了一种用于分析硼化合物的光谱法，根据硼的浓度，会生成浅橙色至红色的络合物。最大吸收波长为577毫米。该方法的灵敏度为分析样品（2立方厘米）中0.001毫克硼。硼浓度与显色样品在0.001至0.15毫克硼区间的光密度之间存在线性关系。对于硼浓度为0.001至0.1毫克的情况，该方法以变异系数百分比表示的准确度在12.4%至6.3%的区间内。该方法可应用的领域是在存在钛、铜和铅化合物的情况下确定的。
