This research proposed to determine the kinetics of toxic metals from the leachate from the infrastructure for the treatment and final disposal of solid waste in Cajamarca when it comes into contact with the soil. The study was carried out at the laboratory level; 100 kg of soil and a volume of 60 L of leachate were placed in a 150 L container to generate the contact of both, the experiment lasted 60 days and was sampled every 10 days in the following periods of 0, 10, 20, 30, 40 and 50 days to later be recirculated. The leachate does not contribute contaminants to the soil, the soil behaves with an adsorbent since arsenic, cadmium, chromium, iron, lead and zinc are metals retained or adsorbed in addition, copper and mercury are metals that the ground does not hold. Regarding the kinetics, it was shown that the reaction rate of iron is higher than the others with 0.012 mg/day and an average adequacy of all metals to the pseudo second order model of 99.58%. It is concluded that the toxic metals in the leachate have a low reaction rate in the soil.
