The hydrogen sulfide problem is of major importance in New Mexico where it has caused many wells to be abandoned. Hydrogen peroxide is a non-polluting, relatively inexpensive oxidizing agent, which has shown promise as a solution to the hydrogen sulfide problem in water supplies. The research ...

The meaning of HYDROGEN is a nonmetallic gaseous chemical element with atomic number 1 that is the simplest and lightest of the elements and that is used especially in the processing of fossil fuels and the synthesis of ammonia —often used before anothe
it is a common pollutant in sewage plants and in agriculture as the process of cleaning the sewage needs the proteins to sediment from the water in which they are suspended. Further processing gives new possibilities
Around 50% of humankind relies on groundwater as a source of drinking water. Here we investigate the age, geochemistry, and microbiology of 138 groundwater samples from 95 monitoring wells (<250 m depth) located in 14 aquifers in Canada. The geoche
The simultaneous solubility of ammonia and hydrogen sulfide in water was measured at temperatures from 313 to 393 K and total pressures up to 0.7 MPa. An adapted Pitzer model is used to correlate the new data. Experimental results are reported and compared to the limited literature data and the...

sulfide photocatalyst (CdS@CAs) (Quan et al.2018). Carrageenan provided a non-toxic sulfur source, i.e., sulfated galactons, that extended across the double helix structure of carrageenan and was integrated by cadmium cations, resulting in photocatalysts with interconnected macropores and mesopores...
贝托莱)had shown thathydrocyanicacid did not contain oxygen, and he later came to the same conclusion with respect to hydrogen sulfide; but these observations carried little weight in the face of the overwhelming unification that Lavoisier's system seemed to promise. ...
For a long time, hydrogen sulfide (H2S) has been considered a toxic compound, but recent studies have found that H2S is the third gaseous signaling molecule which plays a vital role in physiological and pathological conditions. Currently, a large number of studies have shown that H2S mediates ...
