Abstract In this paper, sodium sulfide solution as a simulation of sulfur-containing wastewater, using orange peel as adsorbent, through the change of the absorbance of simulated wastewater to analyze the orange peel adsorbent on the treatment effect of simulated wastewater, to explore its optimal experimental conditions. The experimental results show that the adsorbent has a certain adsorption effect on the sulfur compounds in the sulfur-containing wastewater. With the change of the pH value of the adsorption environment, the adsorption rate has changed. The addition of different chemical modifiers in the water will affect the adsorption and effect of orange peel.

Sulfide Solution

Photoluminescence and Raman spectroscopy are used to study the electronic properties of n-InP(100) surfaces passivated with different sulfide solutions. Such a passivation results in the increase in photoluminescence intensity of the semiconductor evidencing for the reduction in the surface recombination velocity. The increase in the photoluminescence intensity is accompanied by the narrowing of the surface depletion layer, as well as by the increase of the electron density in the probed volume of InP. The efficiency of electronic passivation of the n-InP(100) surface depends on the composition of the sulfide solution.

Sulfide Solution

The ZnS-ZnO composite film was successfully prepared by sulfidation of the as-electrodeposited ZnO film in the aqueous solution of zinc nitrate and hexamethylenetetramine. The ZnO film was electrodeposited on the substrate of indium-tin oxide (ITO) glass, and then the sodium sulfide solution was used to convert the ZnO film into the ZnS-ZnO composite film. The products were characterized by X-ray diffraction (XRD), field emission scanning electron microscopy (FE-SEM), energy-dispersive X-ray spectrometer (EDS) and UVvisible absorption. The experimental results show that the composite film on ITO glass still retained the morphology of as-electrodeposited ZnO coating, and is composed of ZnS with cubic structure and ZnO with hexagonal structure.

Sulfide Solution

Questions asked by several people about our sodium sulfide testing of paint for lead1 make us feel we might wisely add several words of caution about the stability of the prepared solution. Sodium sulfide solutions deteriorate fairly rapidly with age, especially on exposure to air. For this reason, it is suggested that people using the procedure check the odor of the sodium sulfide solution tlley are using, to make sure the odor of hydrogen sulfide is detectable.

Sulfide Solution

The sulfide-silver method of Timm has been a widely used histochemical technique to demonstrate the presence of heavy metals in biological tissue, particularly in the central nervous system. However, the use of this method or its several modifications results in less than optimal morphological preservation and requires embedding the tissue in paraffin or freezing it and cutting it directly onto slides with a cryostat. These procedures can decrease the sensitivity and limit the application of other histochemical procedures, particularly when experiments necessitate processing large specimens or reaction procedures require techniques using free-floating sections. A perfusion-fixation protocol is described that yields sufficient fixation to cut whole frozen blocks of tissue with a sliding microtome, permits the use of free-floating sections, and allows the concurrent demonstration of horseradish peroxidase and acetylcholinesterase histochemistry without loss of sensitivity. The method consists of a short initial exposure to a sodium sulfide solution followed by a prolonged exposure to a combined sulfide-aldehyde fixative solution.
