Calcium phosphate materials have been used increasingly in the past 40 years as bone graft substitutes in the dental and orthopedic fields. Accordingly, numerous fabrication methods have been proposed and used. However, the controlled production of spherical calcium phosphate particles remains a challenge. Since such particles are essential for the synthesis of pastes and cements delivered into...

The treatment of electroplating industrial effluent by coconut husk was carried out by analyzing the physico-chemical parameters of the effluent such as pH, salinity, calcium, magnesium, phosphates, nitrates, BOD3 30C̊ and total solids using standard methods. The efficiency of coconut husk was tested by using it in different quantities such as 25, 50, 75 and 100 grams for five days. As a result,...
