And in Nigeria, where the average yearly salary is $2,000, thousands were drawn to the industry despite its often brutal conditions. In the past, some garbage pickers have died or lost lis when the dump trucks’ hydraulics failed, and the vehicles’ containers crashed down on them.
In addition to my teaching and research in Chemistry and Chemical Engineering, I coordinate and co-supervise several projects. I have also been Dean of our faculty (2006-2009) and am presently the university''s pro-vice chancellor.
In Nigeria, like many developing nations, the resultant environmental problems are legion: aggravated soil erosion, flood disasters, salinization or alkalisation, and the desertifiion due to the effects of shifting agriculture on fragile soils, forest clearing in erosion prone and flood-
The activated carbon Read More In this work, the possibility of using Raphia taedigera seed as a low-cost adsorbent to remove methylene blue () dye from aqueous solutions was investigated. The activated carbon was prepared by carbonization and chemical treatment of the seed with sulphuric acid to produce acid-modified Raphia taedigera seed activated carbon (RTAC).
Alkenes have a Carbon-Carbon double bond(s). They are represented by the formula CnH2n. Here the nuer of hydrogen atoms is double the nuer of carbon atoms present. Examples include Ethene(C2H4), propene (C3H6), butene (C4H8). Note that the

8/8/2020· – CO2: Lung Damage Healer: Elevated carbon dioxide levels prevents injury and promotes healing of lung tissues. – CO2: Skin and Tissue Healer. – Synthesis of Glutamine in the Brain, CO2 fixation, and other chemical reactions: there are many other regulatory and facilitating effects related to uses of carbon dioxide.
Atmospheric concentrations of carbon tetrachloride (CCl4) were removed by bulk aerobic soils from tropical, subtropical, and boreal environments. Removal was observed in all tested soil types, indiing that the process was widespread. The flux measured in field chaer experiments was 0.24 ± 0.10 nmol CCl4 (m2 day)−1 (average ± standard deviation [SD]; n = 282). Removal of CCl4 and
Mechanism and Reactivity - Addition to Carbon–Hetero Multiple Bonds - Introduction - This book explains the theories and examples of organic chemistry, providing the most comprehensive resource about organic chemistry available. Readers are guided on planning and execution of multi-step synthetic reactions, with detailed descriptions of all the reactions. The 7th edition proves again it is a
25/10/2018· In addition, black carbon is associated with hypertension, asthma, chronic obstructive pulmonary disease, bronchitis, and a variety of types of cancer. Nitrogen oxides (NO and NO 2 ) Nitrogen oxide (NO) and nitrogen dioxide (NO 2 ) are produced primarily by the transportation sector.
Carbon dioxide utilisation is an emerging technology which can contribute to the reduction of greenhouse gas emissions by the use of CO 2 to manufacture useful products. While generally un-reactive, CO 2 can be activated, particularly through alysis, to yield a vast array of chemical feedstocks, intermediates and value-added products.
1/9/2011· Vitamin C participates in addition reactions The ascorbate anion form of vitamin C is an enolate capable of forming Michael adducts in aqueous solutions at physiological pH [ 121 ]. There are many examples of covalent adducts of vitamin C, including Michael adducts, with natural products in the plant kingdom, of which ascorbigen is most well known [ 122 ].
