The crystal structure of katayamalite has been determined by Patterson method and refined by the least-squares method using single crystal diffractometer data, giving R = 0.057 for 5785 reflections. Formula: (K,Na)Li.Ca,(Ti,Fe'+,Mn)2[Si60'8].(OH,F)2' Cell dimensions: a 9.721(2), b 16.923(3), c 19.942(3)A, a 91.43(10t, iJ 104.15(11t, 'Y 89.94(10t, space group Cl, Z = 4; or a 9.763(2), b 9.721(2)...

The catalytic ozonation of the herbicide metolachlor (MTLC) was tested using carbon nanomaterials as catalysts. Multiwalled carbon nanotubes were used in semi-batch experiments and carbon nanofibres grown on a honeycomb cordierite monolith were tested in continuous experiments. The application of the carbon catalyst was shown to improve the mineralization degree of MTLC and to decrease the toxi...
