Resumen
In the present work a study was carried out with the objective of evidencing the presence of metals in the algae associated with the roots of the mangroves in the mangrove of Piangüita, municipality of Buenaventura, department of Valle del Cauca. Six plots in the mangrove were sampled and 3 samples were collected for a total of 18 samples on each plot. The samples were analyzed by means of the thermogravimetric analysis (TG) coupled to a magnet called magnetic thermogravimetry (TGM), giving results that indicate the existence of metals obtaining percentages given in two ranges: a lower percentage ranging from 0% to 3% and a higher percentage ranging from 8% to 10% in the algae species Bostrychia calliptera. The results indicate the benefit of the implementation of this new method in this type of studies due to the importance of knowing if metals exist in this ecosystem being a great advance for future studies
