Methods Certain amounts of and Zn were put into the wastewater to produce hydrogen (H2) and the H2 reacted with S2-to form H2S, and sulfuret was separated from the wastewater.
Compund polymer with alumium polychloride and ferrous polysulfate as its main ingredients was used as water scavenging agent in the treatment of dye-house waste water.
Aimed at utilization of iron resources in pyritic slag,the study on production of metallized agglomerate with pyritic slag through coal based DR process was conducted.
Acid intensity of hydrosulfuric acid and stepwise ionization balance were discussed by the use of thermodynamic principle, which are helpful to inorganic chemistry teaching.

Four new materials,such as carbon suspension,sodium sulfonate of polyoxyethylene allyl glycidyl nonyl phenyl ether,vanillyl alcohol,vanillin,etc,in lead-acid storage batteries were reviewed.
The Japanese brand Uniqlo, likewise implicated, responds: The analyses we had access to did not take into account the presence of lead and sulphate in the industrial wastewater.
You'll never find something as powerful as pure sulfuric acid out in nature, since it's so strong that it violently reacts with pretty much anything it touches — including water.

The ceremony of the presidential palace in Bogota was attended by several victims of acid attacks. Among them was Natalia, after whom the new law was named.
Scientists in Australia found microbes known as Thiobacillus concretivorans that lived in, indeed, could not live without-concentrations of sulfuric acid strong enough to dissolve metal.
In doing so, they also produce gases like carbon dioxide and methane, sulfurous compounds called mercaptans, and hydrogen sulfide, which eventually... pass.
