Additive mixing

Sensitivity of the proposed method correlates with molai absorptivity of the cyanine dye. Mixed POMs PMeMo O j (Me=TP+, Sb +, BP+) were chosen as analytical form because of its higher stability as compared with 12-molybdophosphate. Only 2-3T0 concentration of molybdate is enough for complete formation of POM avoiding in this way formation of lA with polymolybdate ions. In addition, mixed POMs are stable in wider interval of pH. Increasing of anion chai ge from 3 to 5(6) is also favorable. Constant absorbance of lA is observed in the acidity range of 0.12-0.28 M. [Pg.87]

Spectrophotometric methods based on an enhancement of the blue color produced on reduction of 12-molybdophosphate (arsenate) in the presence of antimony(III) are widely used for the determination of phosphoms(V) or arsenic(V). However, nature of heteropoly blue, their spectra, mechanism of the reaction are obscure. In addition, mixed POMs were shown as very efficient analytical forms for the determination of P(V) and As(V). [Pg.156]

Nonetheless, since the additives-mixing column will be used for absorption, the whole flowrate of S (0.08 kg mol/s) should be fed to the column. Hence, according to Eq. (3.11b), the outlet composition of Si is 0.0055. The same result can be obtained graphically as shown in Fig. 3.13. It is worth recalling that the target... [Pg.58]

In considering these benefits, the user should not overlook the constraints in using such fluids. They can be summarized as limited wear and corrosion protection (especially with certain metals), increased leakage due to its low viscosity, limited operating temperature range and the need for additional mixing and in-service monitoring facilities. [Pg.864]

AgPh is a colourless solid [144] that is rather insoluble in non-donor solvents and appears to be polymeric (AgPh) (n > 10) in addition mixed compounds (AgPh) .AgN03 (n = 2,5) can also be obtained that involve silver clusters. Mesitylsilver is a thermally stable (but light-sensitive) white crystalline solid in the solid state it is tetrameric (in contrast to the pentameric copper and gold analogues) ... [Pg.308]

With these goals in mind, several investigators have undertaken to set down quantitative expressions which will predict propellant burning rates in terms of the chemical and physical properties of the individual propellant constituents and the characteristics of the ingredient interactions. As in the case of ignition, the basic approach taken in these studies must consider the different types of propellants currently in use and must make allowances for their differences. In the initial combustion studies, the effort was primarily concerned with the development of combustion models for double-base propellants. With the advent of the heterogeneous composite propellants, these studies were redirected to the consideration of the additional mixing effects. [Pg.31]

The above-mentioned mode of reactions changes when the irradiation is carried out in the presence of gases such as oxygen. In this case, energy transfer, the reaction of oxygen with polymer radicals [32] (leading to the formation of peroxy radicals) and other reactions may affect the type and concentration of products formed [33]. The same can be said for certain additives mixed into the elastomer for one or the other purpose. [Pg.855]

All these experiments involve at least three distinct time periods preparation (tp), evolution (tl), and detection (t2) these periods are usually separate by rf pulses. Some experiments (e.g., NOESY, RELAY) further contain an additional "Mixing period, tm, between the evolution and detection periods. [Pg.291]

Brazilian cement plants are relatively modem due to the country s more recent industrialization in comparison with many other countries. For example, the average energy consumption per tons of cement produced in Brazil is 112 kWh/t, while in the United States this is around 140 kWh/t. The efforts of companies in the sector have achieved significant progress in terms of more efficient production systems with lower energy consumption. At the same time, the use of additives mixed with clinker, such as blast furnace slag, also has helped reduce C02 emissions per tonne of cement, because this pollutant is formed during the production of clinker. [Pg.392]

One practical example of demixing that might be attributed to a difference in crystallizability is the incompatibility in blends of polymers with different stereochemical compositions. The stereochemical isomers contain both chemical and geometrical similarities, but differ in the tendency of close packing. In this case, both the mixing energy B and the additional mixing entropy due to structural asymmetry between two kinds of monomers are small. However, the stereochemical differences between two polymers will result in a difference in the value of Ep. Under this consideration, most experimental observations on the compatibility of polymer blends with different stereochemical compositions [89-99] are tractable. For more details, we refer the reader to Ref. [86]. [Pg.17]

Neutralizing additive so/yf/on. Administer this solution promptly. When introducing additives, mix thoroughly, and do not store. Raising pH of IV fluids with neutralizing additive solution will reduce incidence of chemical irritation caused by infusate. [Pg.43]
