A simultaneous spectrophotometric method was developed for assay of uranium, thorium and lanthanum in mixed solutions by absorbance measurements of their arsenazo III complexes at appropriate wavelengths in three different solutions. The absorbances were additive for the three metals in each solutio

An amperometric method for the determination of nitrate in water has been developed. A small addition of acid copper sulfate is made to the sample and a potential pulse sequence is used to measure the current for the reduction of nitrate at an in situ, freshly plated copper surface. The procedure wo
## Abstract The effect of lanthanum sulphate on five __Azotobacter__ strains (4A~7~, 10, 5A~2~, 5A~1~, and 3A~3~) isolated from Allahabad soil consists in a considerable increase in the nitrogen fixation, carbon consumption and in the amount of nitrogen fixed in mg per g of carbon consumed. The pre
