Production And Characterization Of Twelve Different Biochars And Evaluating Their Effects On Soil Health And Plant Growth, Shagufta Gaffar
Production And Characterization Of Twelve Different Biochars And Evaluating Their Effects On Soil Health And Plant Growth, Shagufta Gaffar
FIU Electronic Theses and Dissertations
Biochar has been a topic of growing interest in the scientific community. It is a product derived from carbon rich organic materials through the process of pyrolysis. It has received wide attention as a means to improve soil fertility and crop productivity, absorb pollutants in soil, and sequester carbon to mitigate climate change. Recent research on biochar explores its impacts on the environment with particular focus on use as a soil amendment in agriculture. Biochar produced from different biomass and under different production process effects the environmental and agronomic impacts of its application in different ways. This means biochar can …
Removal Of Pb2+ And Cd2+ From Aqueous Solutions Using Pocl3 Cross-Linked Carboxymethyl Derivatives Of Legume Starch, Ayodele Akinterinwa, Ebun Oladele, Albert Adebayo, Olubode Ajayi
Removal Of Pb2+ And Cd2+ From Aqueous Solutions Using Pocl3 Cross-Linked Carboxymethyl Derivatives Of Legume Starch, Ayodele Akinterinwa, Ebun Oladele, Albert Adebayo, Olubode Ajayi

Starch was extracted from Kwakil beans and cross-linked with POCl3 (1% v/w of starch dry basis [db]). The cross-linked starch (PCS) derivative was carboxymethylated with sodium monochloroacetate (5% to 30% w/w of starch db) to obtain cross-linked carboxymethyl starch (PCCS) derivatives. The derivatives were used in the adsorption of Pb2+ and Cd2+, and the process was monitored using atomic adsorption spectrometer. Carboxymethylation enhanced adsorption of ions (Cd2+, 95% to 96%; Pb, 65% to 94%), and it was more appreciable with Pb2+ than Cd2+ as degree of substitution increased from 0.008 to 0.052. …
