In the results of the sem and xrd tests are displayed in follow. according to the results of xrd test, in terms of structure and crystallinity, copper formation has been detected in all three cases. in position 43, their main peak is clearly visible, as well as in position 51, their second index peak is seen. the code number of each is displayed. the sem image of ph0, which is highly acidic, does not have a well-distributed particle size, small and large particles are seen, but germination has been done in large quantities and has formed many grains. at ph2, the particle size distribution is well formed and the particles are more proportionate in size and the germination rate is acceptable. but in the basic environment, germination is poorly done and the particle size is larger than the previous modes and they are more distant from each other. by comparing these three cases, sample 2 can be recognized as the optimal sample. the shape of the particles in this case is mostly spherical, unlike the other two cases, which do not have a specific pattern. it is also optimal in terms of particle size and germination rate.

Abstract
|
In The results of the SEM and XRD tests are displayed in follow. According to the results of XRD test, in terms of structure and crystallinity, copper formation has been detected in all three cases. In position 43, their main peak is clearly visible, as well as in position 51, their second index peak is seen. The code number of each is displayed. The SEM image of pH0, which is highly acidic, does not have a well-distributed particle size, small and large particles are seen, but germination has been done in large quantities and has formed many grains. At pH2, the particle size distribution is well formed and the particles are more proportionate in size and the germination rate is acceptable. But in the basic environment, germination is poorly done and the particle size is larger than the previous modes and they are more distant from each other. By comparing these three cases, sample 2 can be recognized as the optimal sample. The shape of the particles in this case is mostly spherical, unlike the other two cases, which do not have a specific pattern. It is also optimal in terms of particle size and germination rate.
