What is it about?
Contaminated water with chromium can be treated with mamey apple peel. In this study, trivalent chromium (Cr³⁺) was successfully removed by optimizing pH, adsorbent particle size, and agitation speed. This demonstrates that mamey apple peel is a sustainable, economical, and environmentally friendly alternative for treating contaminated water, especially water of industrial origin.

Why is it important?
The leather tanning industry in Peru generates considerable volumes of effluents with high contents of chromium (Cr), in many cases surpassing the maximum limits permitted by the legislation. Chromium cannot be degraded or removed easily, affecting the biodiversity of soils, rivers, and lakes, and in the worst-case scenario, could be incorporated into the food chain and affect human beings.
Perspectives
The aim is to generate processes that help in the treatment of contaminated water, taking advantage of the adsorbent capacity of food waste such as mamey apple peel, an economical, sustainable and environmentally friendly alternative.
