Phyto Extraction Of Lead From Lead Contaminated Soil

2015-3-14  by plants. [10]. The pH values of different soil samples are shown in Table I. The average pH of 5.6 showed that lead contained in the soil would be available for plant uptake or extraction, thus the possibility of using plants to extract the lead is viable.

Protocol: Extract bioactive substances from plants a

2019-5-7  The extraction mostly is based on a physically transfer from the original plant material into another phase which can be separated by filtration. This can be a liquid or even gas depending on the physical properties of the desired compound and the used method. Most common is for the start to use a mixture of organic solvent as ethanol or acetone. Some target molecule might not be soluble in organic solvents so use water instead. Lab experience sometimes show that changes in pH or the temperature get a better result. This is based on the fact that solubility is depend on this kind of factors. If applying heat first of all be careful because of your organic solvents (flammable and explosive!), also be aware heat might destroy or vaporize some compounds. How much of the solvent should you use? As a rule of thumb use enough to cover the plant material sufficiently, but adding to much just makes your live harder later on. Preferably repeat the extraction after the filtration, some methods already apply this repeated extraction in their setup of apparatus (Soxhlet). In some cases you get decent result with none additional solvent for example to extract dyes from plants
