The XRD patterns showed that the LiMnPO4 sample with ball milling 20h had single ordered olivine structure.
Introduction Olivine structure lithium transition-metal phosphates LiMPO4 (M=Fe, Mn, Co, Ni) have been received much attention as promising cathode materials for next generation of lithium-ion batteries due to their large theoretical capacities as well as chemical and thermal stability[1].
Therefore, Ball-milling is an important auxiliary way for the preparation of pure phase LiMnPO4 with olivine structure and the crystals can grow better through a longer time ball-milling.

The carrier compound of p-amino tetraphenyl porphyrin (p-NH2TPP) was synthesized in our laboratory, of which the structure is shown in Fig. 1.
The recognition mechanism of the p-NH2TPP based plasticized PVC membrane responding to mercury ion (Hg2+) is schematically shown in Fig. 1, indicating that there are possible coordination structure formed between nitrogen atoms of the porphyrin molecule and mercury ion, which is attributed to nice complexation effect between the lone pair electrons provided by four nitrogen atoms of the porphyrin molecule and unoccupied orbitals provided by the mercury ion.
