Biosorción del cadmio con dos especies de Macroalgas (Padina pavonica) y (Acanthophora specifera) en el río arenales parroquia Crucita

The evaluation of the biosorption of cadmium with Padina pavonica and Acanthophora specifera consto of the first stage diagnosed the current situation in the Arenales site of the Crucita parish through the perception of the inhabitants about the contamination of the water, the second determined the efficiency of cadmium removal using Padina pavonica and Acanthophora specifera, a completely randomized design (DCA) was applied, with three treatments and three repetitions (T1 50% - 50% ), (T2 25% - 75% ), (T3 75% - 25% ) , the concentrations of cadmium and the parameters of temperature and pH were determined before and after the process, the third stage consisted in estimating the production cost of the best treatment. As a result, it was obtained that the Arenales site of the Crucita parish is exposed to anthropogenic activities such as wastewater discharges, agricultural activities mentioned by the residents. On the other hand, it was evidenced that the levels of cadmium (0.20 mg/l) exceed the permissible levels of the current national regulations (0.005 mg/l). In addition, it was determined that the treatments with Padina pavonica and Acanthophora specifera removed an average of 90% of cadmium. Deducing that the biosorption system has a production cost of $51.45 and to treat 1 m3 of water it is $245.29. This means that the macroalgae species are highly efficient in the removal of cadmium
