Adsorption can be applied for solution containing low concentration of heavy metals in which helps to investigate the influence of chemical modifications and carbonization of the adsorptive capacities of sawdust foe zinc copper and nickel. This metals help to evaluate ranged between 0.130% and 0.393% while volatile matter range between 0.120% in nickel for unmodified and 0.40% in chemically modified. Results also show highest value of volatile matter (0.401%) in modified while lowest value of (0.120%) was recorded in unmodified by nickel as a catalyst. Highest value of ash content (21.05%) was observed or recorded in chemically modified samples while cowest or least in an modify samples Result of fixed carbon show general increase in carbonized than unmodified and modified. These result show that nickel, copper and zinc have good adsorption capacity for unmodified, chemically modified and carbonized form of sawdust.
Burglar alarm circuit is made up of five major sections. The power supply section; it connects to the source of power, the trigger section which produces trigger current, touch section that controls the supply of power in the circuit, alarm section that sounds when current is supplied to the circuit and the display section constructed with light emitting diodes (LEDs) five (5) digits or alphabets arranged to give inscription “THIEF” soldered on a veroboard. The display section is connected to the alarm section such that its operation depends on the alarm section.
