20 g bone charcoal was immersed in 40 mL
saturated solution of Al[Cl.sub.3], and the modification system was immersed in the ultrasonic oscillator, so that aluminum ion can impregnate onto the bone charcoal better.
The
saturated solution covered with perforated cover as well as 10 holes was made for control evaporation.
The mixture was stirred at 200 rpm for 2 hours and after this time, a
saturated solution of sodium chloride (60 mL) was added and stirred at 200 rpm for 2 min.
The amount of bismuth in the
saturated solution was determined spectrophotometrically at 465 nm complexing it with thiourea in nitric acid medium.
A
saturated solution of NO was obtained by treating 50 g of KN[O.sub.2] with 125 mL of 6 M [H.sub.2]S[O.sub.4] according to the following equation: 3KN[O.sub.2] + [H.sub.2]S[O.sub.4] = 2NO + KN[O.sub.3] + [K.sub.2]S[O.sub.4] + [H.sub.2]O.
In the method of synthesis in emulsion medium, some quantities of
saturated solution of manganese acetate together with the desired oil (peanut oil, olive oil or paraffin) were exposed to ultrasonic waves for a definite time, then precipitations were removed and dried in oven.
After the venting procedure mentioned above, 15 ml of boric acid ([H.sub.3]B[O.sub.3],
saturated solution) was quickly added to each sample.
DEF is a
saturated solution, meaning that at locations where water vapor does escape the closed system, precipitation and crystallization of the urea compound" is likely to occur.
Peterson, a mineralogist at Queen's University, was interested to learn that the Mars Exploration Rover Opportunity had detected magnesium sulfate at the Martian surface, and he got to wondering what mineral phase would appear when magnesium sulfate crystallizes from a
saturated solution at subzero Celsius temperatures.
