TL;DR: In this article, a method for determining small quantities of gold in the range 0.30 μg was developed for determination of antimony with rhodamine B. Owing to the stability of the higher valency of gold no oxidation stage is required; extraction of the complex is only satisfactory with isopropyl ether.

TL;DR: In this paper, a spectrophotometric method for determining fluoride using the aluminium-eriochromecyanin-fluoride complex is described, which can detect as little as 0.02 μg/ml of fluoride and with 0-20 μg in the final solution fluoride can be determined with accuracy of ± 0.6 μg.

TL;DR: A spectrophotomctric study of the reaction between haematoxylm and aluminium to form a complex was performed in this article, where it was concluded that the complex is formed not with haem atoxylin but with haeniatein which is formed from.

TL;DR: In this paper, a method for the spectrophotometric determination of fluoride is described, which can detect down to 0.05 p.p.m. of fluoride on a 10 gram sample with precision of rather better than ± 10% with larger amounts of fluoride.

TL;DR: The application of the aluminium-haematoxylin reagent to the determination of fluoride in sea-water, river and potable waters, and sewage effluent is described in this article.
