In the present paper, biochar from the Laminaria japonica from brackish lagoons (Sea of Okhotsk, Sakhalin Island) was obtained by a stepwise pyrolysis at 500 °C. The properties of concerned biochar (elemental composition, specific surface area, particle size distribution) were studied. It was shown that the Laminaria japonica biochar has 0.2–18 μm particle sizes with a complex branched surface of high microporosity and a specific surface area of 38.6 m2g-1. Aforementioned biochar has the high content of carbon (~60 at%) and high content of oxygen (~34 at.%).
