Analysis of Organic Flocculants in Lead and Cadmium Biosorption in Laboratory-Level Samples

The intention of the work is to evaluate the absorption of lead and cadmium in water, by means of controlled tests, by means of a protocol based on the preparation of 3 types of concentrations of the indicated metals, in a water sample of 1 liter, the used dose of flocculants was made in 5 groups, with varied times of rest of are from 5 minutes to 30 minutes, the method that is presented to evaluate these concentrations, is characterized in being able to use different concentrations, with situations of controlled environment, the most encouraging result was the one that presents a level of concentration of 2. 5 grams of natural flocculant. In order to eliminate cadmium, we have a better response using flocculants based on coconut, grapefruit, tangerine, cucumber and apple fruits.
