چکیده
|
This work is devoted to the modelling and optimization of the growth tracking of the argan tree from southwestern planted in rabat,in the presence of phosphorus and heavy metals (cr,cd). the determination of optimum condition of this growth was realized by the methodology of experimental design: box-behnken. the studied factors that have a major influence on this growth are: the phosphorus concentration (m),the cadmium concentration (ppm) and chromium concentration (ppm). the optimum is reached at a quantity of phosphoric acid equal to 3m,an amount of 28 ppm of cr and 0,775 ppm of cd,comparing with the permissible limit for human consumption.
