1、Research work on the solvent extraction for palladium recovery from acidic solution developed in recent 10 years was described.
2、The sample was digested in the acidic solution and then the calcium reacted with oxalic acid to form calcium oxalate.
3、The main results and conclusions can be summarized as follows:AAO template with highly ordered pores was fabricated in acidic solution by using anodization method.
4、The distribution and transfer character of iron in Liaohe vacuum residue were studied by absorption-separation, acidic solution extraction and mild chemical oxidative degradation of asphaltene.
5、The stability of the red pigment in litchi shell, which was extracted by acidic solution leaching from litchi shell, was studied.
6、I - was obtained from the kelp by alkali fusion, then oxidized by H2O2 in acidic solution, thus we can determine the iodine content by extraction spectrophotometry, which is about 426.
7、The Fourth Step (Final Water rinse) - the acidic solution is flushed and the system is rinsed until the quality of the effluent is equal to that of the influent.
8、Corrosion reactions, with metal dissolution, can occur in both basic and acidic solutions.
