Photolytic Degradation of Herbicide Atrazine by Radiation Ultraviolet (UVC): An Application of Green Chemistry

Valmir Felix de Lima, Francisco Sávio Gomes Pereira, Alexandre Ricardo Pereira Schuler, Maria de Los Angeles P. F. Palha, Antonio Demóstenes de Sobral, Iranildo José da Cruz Filho & Agrinaldo Jacinto do Nascimento Junior · Chemical Science International Journal · 2016

Atrazine (ATZ) is an herbicide of the s-triazines classes used on crops as corn, cotton, soybean, and sugar cane. This work shows the ATZ degradation by ultraviolet radiation (UVC, 254 nm) in a bench-scale annular photoreactor. The initial concentration of the irradiated samples...

Chromatographic Characterization of Potential Feedstocks for Biodiesel Production

Alexandre Ricardo Pereira Schuler, Francisco Sávio Gomes Pereira, Valmir Felix de Lima, Santulla Leide Bernardes Vasconcelos Carvalho & Antonio Demóstenes de Sobral · Chemical Science International Journal · 2016

In this work it was carried out the chromatographic characterisation of vegetable oils (castor, soybean, cotton and jatropha) and animal fats (beef tallow and chicken fat), considered as potential feedstocks for biodiesel production. The samples were transesterefied in microscale...
