Modified clam shell heavy metal adsorbent
Webmodified clam shell powder [33]. Therefore, this paper aims to develop a cheap and eas-ily available modified shell powder adsorbent to adsorb Orange II dye in wastewater, so as to treat waste with the waste. First, shells were made into a soft sponge [34], and then manganese oxides were coated on its surface to study
