The purpose of this research is to study the heavy metal removal from wastewater from laboratory by using adsorption process with firebricks. Waste water was collected among three courses of laboratory such as analytical chemistry principle chemistry and chemistry for engineers. The optimized absorption efficiencies of multi-elements with stirring time volume ratio and temperature were 2 hours 10 g/100 mL and room temperature respectively. It was found that absorption efficiencies of lead (Pb) copper (Cu) zinc (Zn) chromium (Cr) were 65.1 54.8 63.4% and ND respectively.

The objective of this research is to find out the factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP by using questionnaire. The questionnaire is separated into 2 parts the first part is to find out the satisfaction level of each factor and the second part is to find out the effective level of each factor. After the researcher analyzed the data of tested questionnaire of 169 samples students by using Simple Sampling method from 294 students who study in the subjects which are fulfilled by using e-Learning the information were as follows: 1. The satisfaction level of factors is between normal And high the mean of satisfaction level of computer and internet infrastructure factor is normal ( x = 2.81) the mean of satisfaction level of supporting e-Learning system factor is normal ( x = 3.27) the mean of satisfaction level of the supporting personal factor is high ( x = 3.50) the mean of satisfaction level of e-Learning benefit is high ( x = 4.11). 2. The mean of effective level of computer and internet infrastructure factor is very high ( x =4.29) and the mean of effective level of supporting e-Learning system factor is normal ( x =2.98) In concluding to above information the computer and internet infrastructure factor is the factors that affect academic achievements in the subjects which are fulfilled by using e-Learning in RMUTP.

The purposes of this research were to study and compare the company’s Opinion on the potentials of Co-operative Educational Programs of Rajamangala University of Technology Phra Nakhon (RMUTP).
