Organic amendments have been proposed as a means of remediation for Cd-contaminated soils. However, understanding the inhibitory effects of organic materials on metal immobilization requires further research. In this study colza cake, a typical organic amendment material, was investigated in order to elucidate the ability of this material to reduce toxicity of Cd-contaminated soil. Available co...

Recently, sesame oil is highly appreciated by consumers due to its sensory qualities, antioxidants activity and nutritional benefits, despite its high price. Also, the detection and quantification of adulteration both are problem with increasing importance in the consumer’s health and food industry. The goal of this study was to use Fourier transform mid-infrared (FT-MIR) spectroscopy coupled w...

The global method for detection of extraneous oils in different kinds of olive oils as a new method for identification of adulterations is applied using HPLC and GC data by calculations ECN (equivalent carbon number) and R (which is the ratio r ECN42/ r ECN44 for genuineness of all olive oils) according to IOOC method. In this research the global method and ECN42 (difference between the actual ...

Poder calorífico de misturas de biodiesel dos ésteres metílicos de colza (RME) e soja (SME) foram determinados usando um calorímetro de combustão de alta precisão. A dependência dos valores calóricos com a temperatura e pressão no intervalo (273-373) K e (1 a 200) bar foram derivados para misturas de RME e SME de biodiesel B100. Foram propostas equações práticas para o cálculo da correção da te...
