Pot experimental of H2S spent AC adsorbent as a potential green soil conditioner to enhance plant growth / Nur Alis Zainuddin

AC is a carbon-rich stable substance with highly porous material that has been used for H2S removal from gas streams. However, the spent AC generated from the H2S removal may lead to the waste management issue since it is listed as schedule waste in Forth Schedule of the Environmental Quality Regula...
