The living environment is being polluted by toxic waste, particularly industrial waste water
the problem posed is the need to handle this waste water, to minimize pollution effects. The result of the research process wastewater COD with H2O2 soaked bamboo under the catalytic effect of complexes [Co(Acac)]+ was done. Finding the optimal conditions for the wastewater treatment process, after 60 minutes of treatment, COD removal efficiency reached 83.6 percent. The obtained results are the scientific basis for the application to practical catalytic complex.
