Potassium nitrilotriacetate

The sonoelectrochemical deposition of CdSe nanopartides is carried out from an aqueous solution of CdS04, complexed with potassium nitrilotriacetate (N(CH2C02K)3) NTA as a source for Cd, and a selenosulfate solution, (Na2SeS03), as source for Se. The CdSe crystal size could be varied from X-ray amorphous up to 9 nm by controlling the various electrodeposition and sonic parameters. The effects of various electrodeposition and sonic parameters on the properties of CdSe nanopartides are presented in Table 6.3. 

The bis(nitrilotriacetato)zirconium(IV) ion, first detected by Intorre and Martell,1 has been obtained as a hydrated potassium salt by evaporation of a solution containing zirconium oxychloride and the potassium salt of nitrilotriacetic acid. On vacuum dehydration, the anhydrous complex is formed. 

Hydrogen cyanide in pure form was prepared first in 1815 by Gay-Lussac. Earher, in 1782, Scheel prepared this compound in dilute solution. The most important apphcation of hydrogen cyanide is to produce methyl methacrylate for methacrylate resins and plastics. Other products made from hydrogen cyanide include potassium cyanide, sodium cyanide, adiponitrile, methionine, cyanuric chloride, cyanogen, nitrilotriacetic acid, and several triazine pesticides. The compound also is used in small amounts for extermination of rodents. 

Nitrilotriacetic acid (NTA) [N(CH2COOH)3] is a complexant for many metal ions (see Sec. 2.9.1.2 for information on this compound). The sodium or potassium salts of NTA have been used to complex Cd for CD of CdSe from selenosulphate solutions [10,87]. The rate of film growth depends on many factors, as discussed in Chapter 3 experimental details for CdSe deposition from this solution are given in Chapter 2. However, growth times are generally longer than for... 

Polarographic measurements were carried out in an acetate buffer (the assumed pH was 3.66), and concentrations of sulphate and acetate were varied in the presence of l.OOx lO M nickel nitrate and 1.09 x 10 M nitrilotriacetate at a constant ionic strength of 0.2 M (maintained with potassium nitrate). A dropping mercury electrode was used, and polyoxyethylene lauryl ether (1-2 x 10 M) was used as a maximum suppressor. Although results are reported for 15, 25 and 35°C, the assumed pH value for the buffer at 15 and 35°C is not stated. The acetate molarities were varied from 0.025 to 0.100 M at 0.03 M sulphate, and the potassium sulphate molarities were varied from 0.01 to 0.05 M at 0.05 M acetate. The results indicated that for the experimental... 

This preparation gives the potassium bis(nitrilotriacetato)-zirconate(IV) as very small irregular crystals. However, if the solution is evaporated slowly during the recrystallization, large diamond-shaped crystals are formed. In the rubidium and the potassium salts, the two nitrilotriacetate ligands are coordinated to the zirconium in a slightly distorted dodecahedral arrangement. 

Induction of poly(ADP-ribosyl)ation was reported in the kidney after in vivo application of renal carcinogens such as trichloroethene and dichloroacetylene subsequent to DNA double-strand breaks. Potassium bromate and ferric nitrilotriacetate, whose nephrotoxicity is thought to result from ROS formation, both induced poly(ADP-ribosyl)ation with the concomitant formation of DNA double-strand breaks. Recendy, PARP activation has been associated with both gentamicin and cisplatin-induced nephrotoxicity.Both types of nephrotoxicity involve the generation of ROS and the beneficial effects of different therapeutic approaches aimed at reducing ROS formation have been evaluated.
