Abstract
The use of materials and nanotechnology has been increasing in many areas of science including agriculture, these uses include nutrient and fertilizers delivery. Porous materials are the most used for delivery because its properties as big superficial area (greater than 700 m2/g) and surface charge. One of these materials is SBA-15, a silicon material with hexagonal channels and neutral surface charge. At the same biofertilizer use has been increased trying to avoid erosion and water pollution, one of these substances are thiocyanates and isothiocyanates obtained from broccoli (brassica oleracea var. Ital). This study was realized trying to synthesize a material delivery of sulforaphane. Delivery material was synthesized by sol-gel techniques with pluronic P123 as directing agent and tetra ethyl ortho silicate (TEOS) at 35°C and aging step at 80°C and 48 h. These SBA-15 was characterized by transmission electronic microscopy (TEM), infrared with Fourier transform, X ray diffraction. Sulforaphane was extracted from broccoli with acid digestion technique at 70°C, chlorohydric acid 2M. These was characterized by high liquid chromatographic (HPLC). Thiocyanates in three proportion 10, 15 and 25 percent. SNF was adsorbed with reflux at room temperature, for calculate the quantity of solution was made differential scanning calorimetry (CDS) to calculate the loss weight to calculate real SNF adsorbed in SBA-15, which was 15 w%.
