Sentence examples for dissolved aluminium from inspiring English sources
The electrochemical oxidation of dissolved aluminium was studied in alumina saturated cryolitic melts at 1000°C by linear sweep voltammetry and chronopotentiometric measurements.
The experiments performed include: (i) recording and analysis of the main electrical characteristics of the process; (ii) determination of the oxide layer thickness; (iii) anodic gas collection and composition analysis and (iv) electrolyte analysis to determine dissolved aluminium.
It is shown by voltammetry that the species often called "dissolved aluminium" which comes from the interaction of aluminium with molten cryolite is electrochemically oxidized at several electrodes (platinum, nickel, copper, graphite, vitrous carbon).
Table 2 Variation of dissolved aluminium in solution (μg L -1 ) during the experiments (detection limit of the ICP-AES: 1 μg L -1 (37 nM); quantification limit of the ICP-AES: 5 μg L -1 (185 nM)) C.
The authors also recorded higher dissolved aluminium concentrations, and lower pH than streams draining indigenous forest catchments, lower aquatic invertebrate taxa richness in some very acidic streams and an increase in annual sediment yields.
The dissolved aluminium concentrations are close to saturation with respect to gibbsite, (A1(OH)3) and not 7 Å chlorite (micaceous clay) which was identified in the X-ray diffraction analysis of the sediments.
The effect was given a semiquantitative interpretation based on a model of protective film destabilization under high flux of dissolving aluminium ions, and a relatively slow relaxation of the film during the rest time period.
Hydrated aluminium trichloride is prepared by dissolving aluminium oxides in hydrochloric acid.
In a 1798 paper read before the Institut de France, Vauquelin reported that he found a new "earth" by dissolving aluminium hydroxide from emerald and beryl in an additional alkali.
Gaseous phosphine was generated by dissolving aluminium phosphide tablets in a sulphuric acid solution and capturing the evolving gas.
Given our observation of particulate aluminium, a biotreatment in conjunction with a filtration step could result in very significant decreases in dissolved Al.
