Trace elements solution

For the US trace element solution (x 1000) all compounds were subsequently dissolved in 1 L of 1 m hydrochloric acid. The solution was sterilized by filtration through a 0.2 m filter. 1 mL of this solution was added to 1 L of M9 medium prior to usage.

Magnesium sulfate (1 g), kanamycin (50 mg), thiamine (10 mg) and glucose (5 g) were dissolved in water and adjusted to 100 mL volume. This mixture was sterilized by filtration through a 0.2 /im filter and was added together with 1 mL of US trace element solution (see Procedure 2, Section 12.8.2) to the fermenter. 

Most standard hydroponic formulas will include a trace element solution, which may be added directly to the medium or be sprayed on as foliage feeding. Additional supplements may be added at Yj of the recommended amount, followed by an adjustment period of 2-3 days. This gives you time to determine the extent of effect the extra nutrients have had on the plants before more is added. 

Nutrient-Mineral-Buffer (NMB) Solution. Table 1 lists the composition of the nutrient-mineral-buffer (NMB) stock solution used as recommend by ASTM 5271. A trace element solution was also added in order to support biological growth. These solutions were used for all biodegradation tests. Each compound in column one was dissolved in distilled water and diluted to 1L at the concentrations listed in column two. The test medium was formed by adding the volumes listed in column three to 1 L of high-quality reagent water and adjusting the pH to pH 7.0 0.1 with HC1 and NaOH. Approximately 400 mL of the test... 

Add the components of the trace element solution to 85 ml of distilled water while stirring. Bring the volume to 100 ml with distilled water. Store the solution at 4°C.

The experiments were conducted using trace elements solution containing different concentrations. Each treatment was replicated three times. The rhizome and frond were analyzed for inorganic arsenic. Total arsenic contents in soil and plant were determined by instrumental neutron activation analyses (INAA), Nuclear Reactor lEA-Rlm. The sample irradiation was carried out at the nuclear reactor for 8 h and under thermal neutron flux of 2.7 X 10 ncm s subsequently, a decay time of 3 days and 3 h counting time were employed. The radionuclide activities were measured using a gamma-ray spectrometer comprising a hyper-pure GE detector and associated electronic system. The spectra of the samples were measured under the same experimental conditions of the standard photopeak of 657 keV of As. The amount of anion absorbed was calculated as the difference between the anion concentration before and after reaction with the sod-plant systems. 

Trace elements Solutions obtained after digesting samples of about 0.2 g were analysed using either Atomic Absorption Spectrometry (AAS) with graphite furnace atomisation (Perkin-Elmer 4000, HGA 500), or flame atomisation (Varian Techtron), or...
