Activation of waste paper: Influence of varied chemical agents on product properties.

Waste Management, 2022
Waste paper (WP) is rich in cellulose, which can be activated to produce porous carbon, bio-oil, and combustible gases. During chemical activation of WP, the use of varied chemical agents not only generates activated carbon of distinct pore structure but

Chemical warfare agents

Environmental Toxicology and Pharmacology, 2008
Chemical warfare agents (CWA's) are defined as any chemical substance whose toxic properties are utilised to kill, injure or incapacitate an enemy in warfare and associated military operations. Chemical agents have been used in war since times immemorial, but their use reached a peak during World War I. During World War II only the Germans used them in

Ammonia, nitrite transformations and their fixation by different biological and chemical agents

Chemistry and ecology
Nitrogen compounds like ammonia and nitrite can antagonistically affect the environment and human health in many ways. The high rise in demand for food has led to excessive use of fertilisers eventually causing increased losses of reactive nitrogen to ...
