Apricot and Grape Drying Process

All of the reagents used were of analytical grade. Furthermore, acids were purified by sub-boiling distillation in a quartz apparatus. An 18 MΩ cm -1 deionized water-purification system (Millipore, Bedford, MA, USA) was used in all experiments. The stock aqueous solution of sulfur (1000 mg/L) was prepared by dissolving thiourea, sodium sulfate and potassium sulfate supplied from Merck in deionized water. A working solution of sulfur was also prepared from the above-mentioned stock solution by necessary dilution.
Three apricot samples (yellow apricot sample-chemically dried; brown apricot sample-chemically dried; and apricot sample-dried under sun shine) were supplied from Malatya, Turkey. This province leads apricot production, and exports apricots worldwide. One grape sample chemically dried was supplied from Manisa, Turkey. Manisa is the second-biggest grape producer city worldwide. The samples were exposed to SO2 gas for drying. SO2 gas was obtained by the burning of elemental sulfur.
Pd(NO3)2 (Sigma-Aldrich), Mg(NO3)2 (Merck, Germany), Ca(NO3)2 (Riedel-de-Haen, Switzerland), (NH4)3PO4 (Merck, Germany) and, Pd(NO3)2 + Mg(NO3)2, prepared in HNO3, were investigated at 5% (v/v) concentration to determine the best modifier.

Arsenic Speciation and Determination

Check if the same lab product or an alternative is used in the 5 most similar protocols
Stock standard solutions of As(iii) and As(v) were prepared by dissolving appropriate amounts of As2O3 and Na2HAsO4·7H2O, respectively (Merck, Darmstadt, Germany). Working standard solutions were obtained daily by diluting the stock solution with ultrapure water. A chemical modifier solution for GFAAS was prepared by using a mixture of Pd(NO3)2 (1000 mg L−1) and Mg(NO3)2 (300 mg L−1) solutions, both from Merck (Darmstadt, Germany). Choline chloride and citric acid monohydrate both with a purity higher than 99% were purchased from Sigma-Aldrich (St. Louis, Missouri, USA). The chelating agent, diethyldithiophosphoric acid (DDTP) with a density of 1.17 kg L−1 was purchased from Merck. Na2S2O3 and KI (both Merck) were added for the reduction of As(v) to the trivalent state in sample solutions in order to determine total As.

Ruthenium-Promoted Nickel Catalysts on Silica Gel

Check if the same lab product or an alternative is used in the 5 most similar protocols
The Ru-promoted Ni-based catalyst was prepared as described above by incipient wetness impregnations of aqueous solutions of nickel nitrate and ruthenium(iii) chloride (Sigma-Aldrich Co.) on silica gel supports. The loading of nickel was 20 wt% and the molar ratios of Ru/Ni were 0.025 for catalyst samples. The preparation procedure was as described for the unpromoted catalysts synthesized with the impregnation technique. The catalyst was marked as 20Ni–0.5Ru/SiO2 (EG). Similarly, the Pt-promoted and Pd-promoted catalysts were synthesized with the same procedure, and the palladium(ii) nitrate (Pd(NO3)2, Sigma-Aldrich Co.) and diamminedinitritoplatinum(ii) solution (Pt(NH3)2(NO2)2, Sigma-Aldrich Co.) were used as noble metal precursor. The catalyst was marked as 20Ni–0.5Pd/SiO2 (EG) and 20Ni–0.5Pt/SiO2 (EG).
For comparison, the noble metal promoted catalysts obtained from non-pretreated silica support were also prepared with the same procedure and marked as 20Ni–0.5Ru/SiO2, 20Ni–0.5Pd/SiO2, and 20Ni–0.5Pt/SiO2.

Microbial Biomineralization of Metal Ions

A 100 ml of NaC medium was inoculated with 1 ml of K. oxytoca DSM 29614 (OD600nm = 0 1 ABS) and after 3 h of incubation at 30 °C, each culture was amended with 5 mg of Ag(NO3), Hg(NO3)2 or Pd(NO3)2 (Sigma-aldrich, Germany). The cultures were incubated at 30 °C in static mode until colloidal material and the crystals precipitated. Crystals were easily separated by filtration from colloidal fraction and the determination of crystal was performed with X-ray-Diffractometry (Bruker D8, Italy) with 40 kV and 40 mA geometry with Cu Kα (λ = 0.154 nm) radiation. The micro-crystals formed in the cultures added with Pd2+ were observed by optical microscopy (Axio-Imager Z1stand, Zeiss, Italy) equipped with Axiocam MRm 2.8 in transmission and in fluorescence modes. The specimens were stained with DAPI (Fluka, Germany) to observe cells involved in crystal precipitation.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
