The great need to the antioxidants in our life and the increased demand of thiourea derivatives which exhibit great biological activity as anti-inflammatory, antimicrobial, antitumor, and also act as antioxidants and anticorrosive agents leads us to synthesize: N-(2-chlorophenyl)-N’- benzoyl thiourea (CBT) and N-(4-chloro phenyl)-N’- benzoyl thiourea (PCBT) by reflux method and then their metal complexes of CoII, NiII, CuII and ZnII were synthesized by microwave (green chemistry) in hope to get better activities. The structure of ligands and their complexes have been characterized by using elemental analysis, mass Spectroscopy, FT-IR, UV-Vis., 1HNMR and 13CNMR. In this study the synthesized compounds were evaluated for their in vitro DPPH radical scavenging activity. They exerted varying degree of scavenging activity toward DPPH radical with IC50 values between 84 and 250 µg/mL which is considered good and acceptable activity when compared with the activity of standard Ascorbic acid which give IC50 = 14.4 µg/mL. Also the anticorrosion activity of the two synthesized ligands (CBT) and (PCBT) was evaluated on carbon steel coupons by using weight loss method.

Study on Adsorption Properties of Modified MWNTs to Pb2+ in Water
In order to remove the residual harmful lead ion(Pb2+) in water, modified multi-walled carbon nanotubes (O-MWNTs), as a adsorbent, was used to enrich and remove Pb2+ in water samples. O-MWNTs was obtained by mixed acid oxidation. It was analyzed and confirmed that O-MWNTs had been obtained successfully by FITR and TEM. The adsorption property of O-MWNTs to Pb2+ in water was investigated. The adsorption efficiency of adsorbent dosage, adsorption time, adsorption pH and adsorption temperature was investigated, and conclusions are as follows: when pH is 5, the temperature is 20℃, adsorption time is 40 min, and adsorbent dosage is 40 mg/L, the adsorption efficiency was the highest. Adsorption rate of can reach 81.7% under optimal conditions.

Over the last years, the management of municipal solid waste (MSW) has been renovated and modernized. Timely treatment or storage of municipal waste does not, however, solve the problem of the threat MSW may pose for human life and environment. Therefore, projects of modern thermal plants for the processing of municipal solid waste, such as eco-incineration plants, have been launched on the market. It is not only possible to carry out the process of utilization of MSW, but also to obtain renewable energy. The result of MSW incineration is fly ash and bottom ash. In the fly ash composition, there are present chemical compounds such as silicon dioxide, magnesium oxide, aluminum oxide and calcium oxide. The carbonation process is a process in which calcium or magnesium oxide may react with carbon dioxide, forming carbonates. The mineral carbonation is possible with the use of high-calcium fly ash as one of the substrates of this chemical reaction. As a result, it produces carbonates which are not harmful to the environment as well as to humans. The idea of the experiment was to carry out the process of mineral carbonation of fly ash from the thermal treatment plant of municipal solid waste. The whole process was carried out at elevated pressure, and temperatures. After the experiment, several instrumental analyses were performed on the tested samples, such as XRD analysis, SEM scanning electron microscopy and IR infrared spectroscopy. The free calcium content was determined.

Throughout a long time, green chemistry (GC) reviled how a basic scientific methodology and advanced practice can enhance the safe output to human life and the environment without compromising the desired outcomes. For this, advancements in scientific processes have been made in the field of designing safer reagents and solvents, advancement in catalysis and possible development of the renewable feedstock. From the chapters of the past, future chemists are being taught and trained to a wider concept of green chemistry to practice and increase awareness towards human as well as environmental impact. Green Chemistry practice is in high demand and the adherence to the 12 principles of the Green Chemistry concept is growing rapidly. A need for great change in policy, rules and regulations that will force industries, research institutes, academics, and others are still needed more than ever. Moreover, better encouragement, awareness and making an individual person responsible to adapting to a Green Chemistry concept in a real practical way, are needed. Green actions are always louder than green words.

Persistent organic pollutants (POPs) are toxic chemicals which affect the health of human beings and the environment adversely. These pollutants could be transported by wind and water. They could affect people and animals in other countries far from where they were generated initially. POPs persist in the environment for a long time before they are degraded. They bioaccumulate in organisms through the food chain. These chemicals include the organochlorine pesticides and other halogenated organic compounds such as polychlorinated biphenyls (PCBs) and dioxins.The aim of this review is to examine the transport of these pollutants from their point of application and look into their effects on human health. Recent studies reported the gradual introduction of these banned chemicals under different trade names into the environment. Therefore, this review will re- enlighten the public on the dangers in the transportation as well as the harmful effects of these pollutants as they also biomagnify in human. Proper measures on the handling, usage and regulation of these contaminants especially the synthentic organochlorine pesticides should be rekindled worldwide.
