В статье рассматривается вопрос получения активных углей (АУ) из отходов хлопчатника (Gossypium) путем пиролиза биомассы хлопчатника при 500-800оС. Исследованы химико-технологические свойства продуктов, образующихся в процессе пиролиза. Изучены сорбционные свойства полученных карбонизатов.-
Ключевые слова: отходы хлопчатника, карбонизация, адсорбционная способность, cotton wastes, carbonization, adsorptivity
This article is investigating physio-chemical characteristics in manganese sulfate/acetate and amide compounds including thioacetamide, thiocarbamide, thiosemicarbazide in water at 25 °C by isothermal solubility method. System equilibrium was established within 8-10 hours via continuous stirring. For the determination of manganese ion content and nitrogen ions in thiocarbamide, thioacetamide and thiosemicarbazide compounds, trilonometric, Kjeldahl and Duma methods were used.
Activated carbon (AC) was obtained from the cotton (Gossypium malvaceae) processing waste materials. The process was carried out by carbonization at 500–800 °C and subsequent activation at 800 °C by water stream. Cotton biomass is a renewable, low-cost alternative source for textile and food products; however, it hasn't been used for manufacturing of an activated carbon by carbonization in a boiling layer method. Characterization of adsorbents by means of Scanning Electronic Microscope and FT-IR showed that high porosity of carbonized products which was achieved and functional groups were form ...Более
