Abstract:
Lead is a normally occurring metal present in the modest quantity of the earth’s crust.
It is effortlessly absorbed in the earth's hull and the free particles of this metal make distinctive
complexes, when solved in watery media and become the reason to enter the food chain and
cause infections and diseases. Consumption of this heavy metal in form of food affects the
digestive system as well as the respiratory system. It also causes adverse effects on physical
development, cognitive abilities, cardiovascular system, urinary system, and the productive
system in females. Therefore removal of this heavy metal from food has very significant value
for the well-being of all organisms. Pakistan is a farming nation. Over the past few years, the
presence of this heavy metal is noticed in many edible goods, which is posing a serious threat
to human health. Removal of this heavy metal from the food is very complicated and cost
effective process. Keeping this objective in mind the researcher conducted a study to suggest
efficient and inexpensive method of removal of lead from food. There are many different
techniques used for the removal of lead from food but these techniques demand high cost
technology. Pakistan is a developing country and cannot employ such advance and big budget
technologies. The aim of this study is to recommends an affordable and reliable technique.
This study used aqueous solution media through pyrogenic carbon materials (biochar) for the
removal of lead and the modification of these materials. This biochar is comprised of two
methods, Rice husk, and Acacia wood drive. The production of the biochar was collected from
the PMAS-Arid Agriculture university farm house, Rawalpindi, Pakistan. Cross-stream
sampling devices proposed by ECB was used in this study. The result showed that thesis
biochar were useful in the removal of heavy metal lead.Whereas mBAW, and mBRH gave
better results than BAW-1, and BRH-1. Among these mBAW-30K gave maximum Lead
absorption value with 20.574mg/L. This study also provides the Mathematical explanation of
the models, which assists in establishing an understanding of the efficiency of biochar, and
promote the application of biochar technology in water treatment.
