It is one of the "noble" gases. It is characterized by its brilliant green and orange spectral lines. 

Oxalates. Stable oxalates of Pu(III), Pu(IV), and Pu(VI) are known. However, only the Pu(III) and Pu(IV) oxalates are technologically important (30,147). Brilliant green plutonium(III) oxalate [56609-10-0] precipitates from nitric acid solutions containing Pu(III) ions upon addition of oxaUc acid or sodium oxalate. The composition of the precipitate isPu2(C20 2 10H2O. A homogeneous oxalate precipitation by hydrolysis of diethyl oxalate at... 

Chromium hydroxide green is a more bluish and brilliant green than chromium oxide greens. It is quite transparent, and has good strength and excellent stabiUty. It is used in eye makeup and soap.

The compound MgGa204, when activated by divalent impurities such as Mn +, is used in ultraviolet-activated powders as a brilliant green phosphor. Another very important application is to improve the sensitivity of various bands used in the spectroscopic analysis of uranium. Minor uses are as high-temperature liquid seals, manometric fluids and heat-transfer media, and for low-temperature solders. 

The compounds of the t/block elements show a wide range of interesting properties. Some are vital to life. Iron is an essential component of mammalian blood. Compounds of cobalt, molybdenum, and zinc are found in vitamins and essential enzymes. Other compounds simply make life more interesting and colorful. The beautiful color of cobalt blue glass, the brilliant greens and blues of kiln-baked pottery, and many pigments used by artists make use of d-block compounds. 

Bismuth sulphite agar. This medium was developed in the 1920s for the identification of Salmonella typhi in water, faeces, urine, foods and pharmaceutical products. It consists of a buffered nutrient agar containing bismuth sulphite, ferrous sulphate and brilliant green. 

Escherichia coli (which is also likely to be present in material to be examined) is inhibited by the concentration (0.0025%) of brilliant green used, while Sal. typhi will grow luxuriantly. Bismuth sulphite also exerts some inhibitory effect onE. coli. 

Green S (E 142, Cl Food Green 4, Brilliant Green BS) is a triarylmethane dye, with the chemical name sodinm N-[4-[[4-(dimethylamino)phenyl](2-hydroxy-3,6-disnlfo-l-naphthalenyl)-methylene]-2,5-cyclohexadien-l-ylidene]-N-methylmetha-naminium. The calcium and potassinm salts are also permitted. Green S is a dark bine or green powder or grannies, solnble in water, slightly solnble in ethanol, with a maximum absorption in water at 632 nm = 1720). It is not permitted as a... 

Fresh Lu(Pc)2 films (likely to be singly protonated,40 although this issue is contentious33,41), which are brilliant green in color (Amax = 605 nm), are electro-oxidized to a yellow/tan form (Equation (l)).35,38,4lA further oxidation product is red,35,38,41 of unknown composition. 

However, the formation of these products does not appear to play a critical role in the decision as to whether the 425 nm and 480 nm maxima are due to different states of the same molecule or to different compounds. It was reported that special care was taken to ensure the purity of luminol and of 3-aminophthalate 109>. In commercially available 3-amino-phthalic acid a yellowish impurity exhibiting brilliant green fluorescence was detected 109> this substance also formed in neutral solutions of pure 3-amino phthalic acid and crystallized from these solutions in yellow crystals. The structure of this substance was determined to be 53 its absorption spectrum has a maximum at 388 nm the fluorescence maximum is at 475 nm, with a fluorescence quantum yield of about 0.75 in DMF i 9).
