background: previously described methods to separate dissolved u(iv) from dissolved u(vi) under acidic anoxic conditions prior to laboratory analysis were ineffective with materials currently available commercially. three strong anion exchange resins were examined for their efficiency in separating, recovering, and preserving both redox
sand castings are produced in specialized factories called foundries. over 70% of all metal castings are produced via a sand casting process. the six steps in this process are: (i) place a pattern in sand to create a mold. (ii) incorporate the pattern and sand in a gating system. (iii) remove the pattern.
the problem of separating convolutive mixtures of unknown time series arises in several application domains, a prominent exam-ple being the so-called cocktail party problem, where we want to recover the speech signals of multiple speakers who are simulta-neously

and complex mixtures, but in some comparison the hplc methods were found to be similar to that of the iec. 1 introduction moore and stein [17, 18] devoted plenty of time to separation and very precise determination of amino acids in the middle of the 20th century. in 1958, together with spackman they published the description of the automatic amino
an important feature of the tph analytical methods is the use of an equivalent carbon number index (ec). the ec represents equivalent boiling points for hydrocarbons and is the physical characteristic that is the basis for separating petroleum (and other) components in chemical analysis.
the first method exploits both correlation and pseudo-correlation matrices of the mixtures in the frequency-domain while the second method only uses correlation matrices.

pulses. injectoran injector is placed next to the pump. the simplest method is the use of a syringe, and the sample is introduced into the flow of eluents. the most common injection method is based on sampling loops. the use of the autosampler system (auto-injector) is also widespread, allowing repeated injections on a set schedule.
a method for separating h 2 s into h 2 and s with some input of energy would be of great benefit to the petroleum refining industry. the recovery of both h 2 and s through the direct conversion of h 2 s to these two products could be accomplished using a high-temperature, h 2 -selective membrane.
the lowest values, i.e., 30.5% and 40% reduction compared to the reference mixture, were achieved for 28 days of flexural and compressive strength for concrete with substitute of 20% of waste plastic.

majority of matter is made up of mixtures. there are different separating techniques used in separating a mixture of solid and liquid, and mixture of substances with different adsorptive properties. the methods of separating techniques are filtration, evaporation, chromatography and distillation.
methods: this study has been designed to evaluate the efficiency of three acid digestion methods using different solvents. five samples were digested with three different acid digestion methods namely method a (a combination of nitric-perchloric acids hno 3–hclo 4 in a ratio 2:1), method b (only nitric acid hno 3), and method c (a mixture of
