Diethylene-triamine pentaacetic acid

Diethylene triamine pentaacetic acid is a chelating agent that sequesters metal ions so they cannot combine with other ingredients in a product. [Pg.51]

Diethylene triamine pentaacetic acid is used in soaps as a water softener, and to protect dyes and perfumes from combining with metals in solution. [Pg.51]

Stripping solutions contain large amounts of guanidine carbonate (0.5-1 M) and diethylene-triamine-pentaacetic acid (DTPA) (124). Though,... [Pg.140]

The treatment of complex ion equilibria in solution is analogous to the treatment of weak acids. One of the best known chelators is the well-known EDTA (ethylene diamine tetraacetic acid). The metal stability constants for EDTA are very high, which indicates strong complexes. Various other compounds are available with high metal-stability constants for agricultural or environmental uses. Some of the more important ones are DPTA (diethylene triamine pentaacetic acid), CyDTA (cyclohexane diamine tetraacetic acid), EDDA [ethylene diamine di (0-hydroxyphenyl acetic acid], or Chel-138. [Pg.92]

PLEX PC is a modified diethylene triamine pentaacetic acid calcium-sodium salt. It contains a minimum of 30.0% active agent. The chelating values (CV) are in the table below. [Pg.623]

Kinetics of release of pre-adsorbed Zn on addition of diethylene triamine pentaacetic acid was also studied. [Pg.1011]

The micronutrient cations can be estimated in a single extraction with diethylene triamine pentaacetic acid (DTPA) which has excellent chelating property with the micronutrient elements. Adequate precaution must be taken against any likely contamination from the reagents and glass wares in micronutrient assay work. Only double distilled water should be used. Specific hallow cathode lamps for each elements are used on AAS and requisite standards for instrument calibration are prepared as per instructions in the operation manual. [Pg.125]

Fig. 12. Trace element/Ca ratios of foraminifera subject to different cleaning procedures, (a) Mn/Ca, (b) Mg/Ca and (c) Sr/Ca. Samples cleaned using procedure A were subject to ultrasonication in methanol, oxidation and a weak acid leach. Those cleaned using procedure B were subject to additional reductive cleaning, and those cleaned using procedure C were subject to additional reductive cleaning as well as cleaning in DTPA (diethylene triamine pentaacetic acid). DTPA removes refractory phases rich in Ba and the rare earth elements (e.g. Haley Klinkhammer 2002). Note that the introduction of the reductive cleaning step significantly lowers Mn/Ca and also lowers Mg/Ca. Reductive cleaning has no resolvable effect on Sr/Ca. DTPA has little effect on Mn/Ca, Mg/Ca or Sr/Ca. Error bars (where visible) represent the standard deviation of the mean of two (0. universa) or three (G. conglomerata) separate analyses. Data are from Hathorne (2004). Fig. 12. Trace element/Ca ratios of foraminifera subject to different cleaning procedures, (a) Mn/Ca, (b) Mg/Ca and (c) Sr/Ca.

Figure 12.9 shows the effect of oxidizing and reducing conditions (redox potential) on the distribution of copper among several selected forms in river sediment. Under oxidized conditions, the copper was primarily tied up with iron because the extractant nsed to remove the reducible fraction primarily extracts the iron fonnd in the insoluble ferric form that is microbially reduced to a more soluble ferrous form, which would release bound copper. The insoluble organic copper decreases as the amount of copper coprecipitated with the increase in iron oxidation. The diethylene triamine pentaacetic acid (DTPA) extractable Cu showed little change with redox condition. [Pg.492]
