  1. 1. Scrubbing of sulfur dioxide from secondary process gases in a copper smelter

    University essay from KTH/Kemiteknik

    Author : Obiora Okolo; [2021]
    Keywords : sulfur dioxide; scrubbing; smelter; process industry; flue gas desulfurization; svaveldioxid; skrubbning; smältverk; processindustri; rökgasavsvavling;

    Abstract : Processindustrin är den största källan för utsläpp av svaveldioxid (SO2) i Sverige, vilket även inkluderar icke­järnmetallindustrin. Kopparsmältverket Boliden Rönnskär har ett miljötillstånd som tillåter SO2­-utsläpp på maximalt 3500 ton/år, en gräns som Rönnskär har legat nära under de senaste åren. READ MORE

  3. 2. Investigation of the Metal Content in Cress Seedlings fed with increased Concentration of Lead & Iron Solutions

    University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

    Author : Nikita Burton; [2020]
    Keywords : Cress; iron; lead; metals; acidified digestion; MP-AES; ICP-MS;

    Abstract : Metals are essential nutrients for plant health, but not all metals are necessary and can sometimes be harmful towards plants depending on factors such as species, elemental composition in the soil and concentration of a metal. Iron (Fe), which is one of the most abundant metals in the earth’s crust is also one the most important nutrients for plant growth, as it is responsible for metabolism. READ MORE
