Example 1

The Cu-based catalysts were synthesized by incipient wetness technique. The chemicals used in the synthesis include Cu(NO3)2.2.5H2O (Alfa Aesar), NORu-3NO3 (Alfa Aesar), Ga(NO3)3.xH2O (Alfa Aesar), Pd(NO3)2.2H2O (Sigma-Aldrich), AgNO3 (Sigma-Aldrich), SiO2 (CAB-O-SIL EH-5, CABOT), ZSM-5 (CBV2314, Zeolyst), ammonium zeolite mordenite (20:1 mole ratio SiO2:Al2O3, Alfa Aesar, noted as MOR). In a typical synthesis procedure, m(Cu)/m(support) was set at 10 wt %, whereas the content of Ru, Ag, Ga and Pd was fixed at 1 wt %. After introducing metals by incipient wetness technique, samples were air dried at room temperature overnight then continued dried in an oven at 110° C. overnight. The obtained samples were calcined at 550° C. for 4 h. Before the acetylene dimerization reaction, catalyst was reduced at 500° C. for 2 h.

Both target amounts of Pd(NO3)2·2H2O (Sigma Aldrich) and metal precursors (Sigma Aldrich or Alfa Aesar) were dissolved together in the 40 mL distilled water with Vulcan XC72 (Cabot Co.). The solution was stirred for 2 h at high speed and subsequently sonicated for 1 h to disperse whole materials uniformly. Then, as-prepared NaBH4 solution (10 times of moles of metal precursors) in the 45 mL distilled water was introduced to the solution dropwise for 45 min (1 mL min−1) to reduce the metal precursors to the metals under vigorous stirring. After adding NaBH4 solution, stirring process was carried out for 2 h. Thereafter, the catalyst was filtered and washed by the distilled water several times to get rid of residual ions of the precursors. Finally, the catalyst was dried at 100 °C in air overnight.

Two kinds of supports were used in this study: biogenic silica and commercial silica. Cornhusk (Zea mays) residues were obtained from a local farm in the Ashanti region, Ghana, in the form of five round bales, each approximately 50 kg, for a total of 250 kg. Upon collection, they were washed in an extractor (STAHL ATOLL 290 E, Gottlob Stahl Wäschereimaschinen GmbH, Sindelfingen, Germany) at 50 °C for 2 h to remove dirt and soil particles. Commercially available support (99.89 wt.% SiO2, CWK Köstropur® 021012, Chemiewerk Bad Köstritz GmbH, Bad Köstritz, Germany,) was also purchased and used as a benchmarked catalyst.

Optimizing GFAAS Conditions for ALF Analysis

Check if the same lab product or an alternative is used in the 5 most similar protocols
Prior to analysis, all glass and plastic recipients were immersed in a 10% (v v -1 ) HNO3 solution for 24 h followed by rinsing with ultrapure water (resistivity higher than 18.2 MΩ cm). All solutions were prepared with HNO3 previously distilled in a quartz sub-boiling system (Distillacid, Berghof). The aqueous standard solutions employed were prepared using 1000 mg L -1 of each element Cu, Cr, Mn and Pb (SpecSol) in 1% (v v -1 ) HNO3 solution. Stock solutions of each chemical modifier used, Pd(NO3)2 and Mg(NO3)2, were prepared by dissolving 0.6259 g of Pd(NO3)2.2H2O (Sigma-Aldrich), and 2.6709 g of Mg(NO3)2.6H2O (Sigma-Aldrich,) in a 25 mL 1% (v v -1 ) HNO3 solution.
The ALF composition is the closest to human pulmonary environments, simulating the acidic cellular conditions under the phagocytosis process and it was prepared as described by Colombo et al. 18 (Table S1).
In the experiments of the GFAAS instrumental conditions optimization, the recovery parameter was evaluated, being obtained by the ratio of the signal from ALF samples previously spiked with the analyte and the signal from the standard analyte solution (reference solution), both in the same concentration level. In these experiments, the final volume of ALF employed was about 5 mL.

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.
