Hello! I will represent Latvia in the SJWP 2026 together with Marta Liepiņa. We researched wastewater purification from heavy metals using broadleaf cattail (Typha latifolia).

Wastewater purification from heavy metals using broadleaf cattail (Typha latifolia)
Wastewater often contains harmful heavy metal compounds that pose risks to both human health and ecological balance. This study explores an environmentally friendly and cost-effective alternative for removing heavy metals, specifically copper Cu(II) ions, from wastewater using the biomass of the broadleaf cattail (Typha latifolia) and its associated microorganisms. The research also examines promising methods for heavy metal Cu(II) desorption, allowing the biomass to be reused, safely and responsibly disposed of, and enabling the recovery of a concentrated metal ion solution. The data obtained summarizes heavy metal Cu(II) absorption and desorption efficiencies at different copper ion concentrations. From the obtained absorption efficiency results, it can be concluded that the stems and roots of broadleaf cattail (Typha latifolia), together with the…
